Re-installing an iPhone App

I was asked a question recently about re-installing an app on an iPhone, which while relatively straightforward does include a few steps which may not be obvious. So, using our favourite TodUhr

Unchecked apps don't sync. Tick that box!

application as an example, here’s how it goes. Note that the general procedure is the same whether you’re using an iPhone 3G/3GS/4 we just need to allow for the fact that the 3G/3GS phones don’t support the application ‘switcher’.

  1. For iPhone 3G/3GS users, switch off the phone then switch it on again. This is just to make sure the app isn’t running when you try to delete it. iPhone 4 users can simply kill the app by double-tapping the Home button then finding the relevant app icon in the task list, pressing and holding the icon, then tapping the little ‘no entry/delete’ symbol top left of the icon.
  2. iPhone 4 users should then tap the Home button once to close the app switcher list.
  3. Now locate the application on your phone and press and hold the icon until it starts ‘wobbling’.
  4. Tap the little ‘x’ symbol that appears at the top left of the icon.
  5. You will see a pop-up message asking if you want to delete the app and all it’s data from your phone. Tap OK.
  6. Press the Home button once to exit the application edit mode.
  7. The next time you sync your iPhone with iTunes, the check-mark next to the application you have just deleted from the phone will also disappear. The app will still be in your iTunes library, however iTunes will assume that because you’ve deleted it from the device that you no longer want to sync it back to the device (hence why iTunes automatically un-checks it).
  8. Making sure your iPhone is connected to your Mac or PC, click on your device in iTunes then click on the Apps tab.
  9. Scroll through the list of apps to be sync’ed with your iPhone until you find the one that you deleted earlier. You should find that the little box to the left of the application name is blank.
  10. Click the box once to make sure it is ‘ticked’.
  11. Now re-sync your iPhone with iTunes and the app should be copied back to your device.

It is possible that the app may be damaged on your device, so this may help by effectively ‘re-installing’ it, and the above steps will be much the same for an iPad/iPad 2/iPod Touch depending on what version of iOS they are running.If the application file (ipa file) in iTunes itself is damaged, then you would need to delete the app from within iTunes and then re-download it. This is necessary because if you attempt to download it without deleting it first, the Buy/Free button in iTunes will simply say ‘Downloaded’ and not let you do anything else. For a paid app I am assuming you won’t get charged a second time for it, but that is something I’ll have to check.

Note that I’ve never experienced a corrupt application file first hand and I am assuming that if this did happen then iTunes or the iPhone itself would tell you there’s a problem.

PS… here’s one other thing you might try to nudge an app into installing/running if there’s a problem with the iPhone. It’s a soft reset which you can do as follows:

  1. Press and hold the Home button.
  2. Keeping the Home button pressed, press the on/off button on the top of the iPhone and keep it held.
  3. After a few seconds the ‘Slide to power off’ message will appear – KEEP BOTH BUTTONS HELD DOWN.
  4. After a few more seconds the iPhone screen will go blank and the Apple logo will appear.
  5. Release both buttons.
  6. The Apple logo will stay on screen for a while as the phone reboots. On my iPhone 3G that takes about 60 seconds.
  7. Eventually you’ll be prompted to enter your unlock code or the Home screen will appear (depending on how your phone is configured).

There’s an Apple article on the technique here.

iPad + iOS 4.2.1 = Frustration

Sorry but this is a little rant about the latest and greatest version of iOS 4.2.1 on my 32Gb WiFi iPad. You see up to the point just before I upgraded, my iPad was marvellous. Either at home on my WiFi network, or out and about with my Three UK MiFi mobile hotspot, anything requiring internet access was a breeze. Applications like Osfoora and WeatherHD would update almost instantly, web pages would load quickly, even my LogMeIn Ignition worked really well.

But then that fateful day came in November when the much anticipated iOS 4.2.1 update hit the Apple servers. Multi-tasking (of a sort), folders, AirPlay, AirPrint (ok with a helping hand from Printopia in my case), but all really useful stuff. Like many others I’ve heard about including two iPad owning friends, the iOS 4.2.1 update on the iPad wasn’t quite the usiual ‘it just works’ Apple experience. iTunes got part of the way through the update before it decided to ‘hang’. I left it like that for 2.5 hours (yes, two and a half hours!), but no joy. The iPad was in limbo and I eventually had to force quit iTunes and start again. Much later that evening, the iPad was up and running with iOS 4.2.1 and that’s when my WiFi woes started.

No WiFiAt first I thought it was my internet connection at home, but using my MiFi instead of my home broadband produced the same results. The iPad would show itself as being connected to a WiFi network with a strong signal, but web pages would start loading incredibly slowly and apps would take forever to update. Then the connection would drop completely and Mobile Safari would complain of timeouts, apps would tell me I wasn’t connected to the internet and all the while the iPad showed itself as being connected with a strong WiFi signal. Rebooting my router or MiFi made no difference, what’s more my Mac was still working perfectly through the same WiFi connection. Eventually I twigged that restarting the WiFi on the iPad would temporarily fix the problem. Initially this was switching the iPad off then on again, but then I discovered that just recycling the WiFi by turning Airplane mode on for five seconds then off again would do the trick. But the problem would always return, sometimes as soon as five minutes afterwards and sometimes I would get a full 30-45 minutes of working WiFi before it would tail off again and eventually stop.

Searching the internet has revealed that a lot of people are experiencing the exact same problem – intermittent and slow WiFi since upgrading to iOS 4.2.1. Some surveys I’ve seen suggest that it’s as many as 25% of users are having this problem, and it clearly is a problem. Whether it’s related to a particular ‘batch’ of iPads, or some curious combination of circumstances, who knows. I know three other people with iPads and two of them have the same problem, making that 75% of the people I know. I know, it’s a very small sample and for reference one of my friends who has the problem actually had a smooth upgrade without iTunes hanging.

As incredibly frustrating as this is, it wouldn’t be quite so bad if Apple wasn’t being it’s usual taciturn self when it comes to problems. What problems? Having browsed the numerous complaints on the Apple Support Forums, there doesn’t seem to be any acknowledgment at all from Apple that there’s a problem. Even a simple “we’re not saying there’s a fault but we are investigating” would help. In all honesty, I’d be very surprised if Apple weren’t aware of the problem and are doing a little investigation, but engaging your customers a bit better when there’s issues like this would push their already high customer satisfaction ratings up from the low 90’s towards that magical 100%, well ok 99% ‘cos there’s always someone!

Surely that’s something that Steve Jobs and Co would love to do? I know it would make me happy… well happier knowing a fix is on the way.

Here’s a thread about the issue on the Apple Support Forums – HERE

iOS 4.2.1 Airprint Frustration

Strangely enough I didn’t pay much attention to the release of iOS 4.2.1 even though I have a WiFi iPad, an iPhone 4, my old iPhone 3G and an Apple TV (2nd gen). Sure I was aware of the basics like improved speed on the iPhone 3G (I’ve yet to notice it), folders on the iPad, playing video from the iPad on your Apple TV, ‘multitasking’ and of course AirPrint.

So I decided to check out AirPrint and had a quick look at the Apple web site…

“AirPrint makes it simple to print email, photos, web pages, and documents right from your iPhone, iPad, or iPod touch. A few taps is all it takes to go from viewing it onscreen to holding a printed copy. There’s no software to download, no drivers to install, and no cables to connect.”

Well that looks straightforward enough. I guess so long as my printer is switched on and visible on the network (it’s shared by my Mac Pro) then I’ll be good to go. I fired up my iPad, loaded Pages, selected Print and hey presto…. ‘No Printers Found’. What do you mean no printers found? I can see it. The little green light is on. In my System Preferences on the Mac it definitely says it’s shared. What’s going on? Time to Google the answer and discover the truth behind Apple’s rather over-simplified statement. That’s right, seems there’s a key phrase missing from Apple’s web page, so I have ‘amended’ the AirPrint feature point on Apple’s iOS web page for you. Hope it’s a little clearer now…

AirPrint Clarified

There, that's better...

Obviously my Canon ip4000 doesn’t qualify, and given that it prints great photos, letters, etc., I have no intention of replacing it. Maybe there are more AirPrint-enabled printers on the way. Perhaps Apple will push an update in the future that ‘enables’ a greater range of existing printers to be used, who knows. What I do know is that their glib statement about just ‘click & go’ is somewhat misleading. Judging by the large number of queries from people who have been asking why AirPrint doesn’t work for them, it seems like a lot of people were caught out by this. Now I’m an IT person of sorts and I should know better (and do my research more thoroughly), but you can’t expect the average Joe to read that statement and then go off hunting for clarification – they just want to print.

Rumour has it that broader printer support was going to be included but that it got pulled at the last minute. Still, if Apple is able to co-ordinate the release of iOS 4.2.1 worldwide, then you’d think they could adjust a little bit of text in a web page just to make things clear? Well they do… IF you go to the iPad page, click on the AirPrint link, then scroll to the bottom of the page. That’s marketing at it’s best – big up the features in your headline and then hide the gotchas away – behind a door marked ‘Beware of the tiger’!

PS – I am aware that there is a ‘fix’ for this problem that involves downloading three files to your Mac and overwriting a couple of system files, but I’ll wait for the official fix – if it happens.

I’m being tempted away from my Mac…

XP desktopMy step-mother has a Sony Vaio laptop that has to be about 5 or 6 years old and runs Windows XP. Her needs are simple, but she comes from a generation that really doesn’t get computers. She refers to the hourglass timer as a ‘christmas cracker’ and has no idea that Windows Explorer and Internet Explorer are entirely different animals. When I built the laptop for her I loaded it with all the necessary security software, but for someone who doesn’t have the intuition about what one should or shouldn’t do (or rather click on), then it’s a recipe for disaster (aka repeated ‘support’ calls).

Every so often I completely rebuild the laptop, but it’s only a stay of execution and it’s becoming obvious that she needs something a bit more modern, a bit more simple and a bit more robust. So I’m thinking about an iMac, a Mac Mini or perhaps even an iPad. Email, a very small amount of web browsing and online shopping, being able to look at photos and the odd brief document are all she needs and it seems that any one of these devices will serve her well. To this end I picked up an iPad for her, the thinking being that it was the one device that would do all of the above, be intuitive to use and free her up from locking herself away in a room (much to my dad’s dismay) when she needs to ‘compute’.

It’s a 32Gb WiFi model and I’ve been using it to see what it can do before offering it as her new computing partner (of course she’ll still need a PC/Mac running iTunes plus a wireless router, but that’s another story). I have to say that having had no intention of buying one myself, as I already have my Mac Pro and iPhone 3G, I am now rapidly changing my mind. Firstly, I read a lot of RSS news feeds using Vienna on the Mac. I do occasionally use Google Reader but Vienna gives me the clean interface I want and if you want a free (and ad-free) news reader for OS X then this would be my recommendation. But then there’s NewsRack on the iPad. I can laze on the sofa in the lounge and flick through my RSS feeds so easily, browsing in detail the articles I’m more interested in, or adding them to InstaPaper for later. Yes there are other news readers for the iPad, but NewsRack has a clean and intuitive interface that just seems really natural when you’re coming from an OS X (or even Windows) based reader. What’s more it does this whole Google Reader sync thing if you feel the need to read news feeds on multiple devices, plus has many other features besides.

Then there’s the mail app on the iPad. It works exactly the way you think it should and I find I can process 95% of my mail here, just resorting to the Mac where I need to do something a little more complicated. The result is that I can now go for days without using the Mac to do these routine things. There’s other things too… Weather Pro HD gives me detailed weather forecasts rather than having to use WeatherDock on the Mac. Osfoora HD on the iPad is now my preferred way of monitoring Twitter, while Nambu is my choice when on the Mac, and if I want to read a PDF I’ll generally be doing it in GoodReader on the iPad rather than in Preview on the Mac.

IMG_0013It’s not that the apps on the Mac aren’t any good, in fact they’re the best ones I’ve found in my years of Mac usage. It’s just that I don’t have to go and sit upstairs in front of the Mac to dip my toe into the computer world. What’s more, I’ll often find that when I start using the Mac just to do a quick email for example, I’ll often get sidetracked and then ‘waste’ an hour or two doing something I hadn’t intended to. With the iPad I pick it up, do the email or read the news then put it down. Having said that, the games on the iPad are pretty distracting!

Now don’t get me wrong, the Mac Pro is still great, and for content creation the iPad doesn’t come close. For starters, the WordPress app for the iPad is a bit of a lame duck if you ask me, and I’d far rather use the WordPress dashboard on the Mac to create or edit blog posts. Similarly, for photo editing and processing, long documents, spreadsheets, downloading, listening to music (even though SnowTape and Spotify can run on the iPad), and for many other more involved tasks, the Mac is still king.

So, when my step-mother takes this iPad off my hands will I be tempted to spend the money on getting one myself? Do bears sh*t in the woods?! Hell yeah…  Of course I could just recommend she gets a cheap Windows 7 laptop for her needs and keep this one, but I suspect the whole Windows support cycle thing will just start afresh, and I’m not sure my nerves could take it. Besides, if she has the iPad then there’s always AppleCare to ease my burden 😉

By the way, in case you’re interested here’s a few of my favourite iPad apps (note, clicking on links may prompt you to open iTunes):

  • WeatherPro HD – detailed weather for your location for the next seven days.
  • Pages – I’m just a sucker for being able to write stuff wherever I am, and as a Pages user on the Mac…
  • Life Browser – iPad Safari is good, but in many ways I prefer this.
  • Instapaper – great way to save web pages for later consumption.
  • NewsRack – elegant and intuitive RSS reader with all the right features.
  • Evernote – wouldn’t be without it, whatever device I’m using. (I think my brain is backed up to Evernote!).
  • DropBox & SugarSync – love ’em both and can’t decide which I prefer.
  • Osfoora HD – does all a Twitter client needs to do for me on the iPad (and lots more besides).
  • Magic Piano – I’m no impresario but this makes me sound like one!
  • GoodReader – is to PDFs what FireFox is to the web.
  • IMDb – how cool to watch a film and be able to learn more about it as you watch?
  • eyeTV – let’s me wirelessly stream recordings on the Mac to my, ahem… the iPad. It can do live TV too, but I’ve got a TV for that. (Note, you need eyeTV on your Mac for it to work).
  • tChess Pro – attractive and challenging chess game with all the features I need to remind me I’m rubbish at chess!
  • Angry Birds HD – ok you have to catapault various types of birds into pigs. Sounds daft, but it’s very entertaining and the sound effects are just lovely.
  • Words with Friends HD – sort of a multi-player (across the web) Scrabble clone. (Multi-player as in my friends can mock me with their prowess!).
  • Real Racing HD – first person racing game with incredible graphics and gameplay.
  • Hexius – a bit like Bejewelled but perhaps more challenging and complex… and with multi-player capabilities.
  • Soosiz HD – a platform game where gravity isn’t always what you’d expect. Good fun.
  • Monkey Island 2: SE – Monkey Island meets the iPad, this game is entertaining, funny and looks fantastic.
  • Osmosis for iPad – mesmerizing, challenging, addictive, relaxing, a must if you have an iPad.

IMG_0012And one final word on usability. The father of a friend of mine has Parkinson’s disease and finds it extremely difficult to interact with the world around him. Trying to show him photos on a laptop and to let him feel he has any sort of control was frustrating for him, and printed 4×6 shots were just too fiddly (let alone time consuming to create). It was great to put an iPad on his lap and to see him smile and enjoy the photos in a way in which he can be in control.

iPad – Little known difference between UK and US…

Since I started using an iPad, one thing has been bugging me – the calendar. More specifically, what is shown as the first day of the week when you have the calendar in week or month view. Being brought up in the UK, for some reason I was always told that Sunday was the first day of the week. So, when I got my shiny new iPad and spotted that the week and month views start on a Monday, I set about trying to find how to change it.

Maybe it’s linked to the fact that my iPad calendar syncs with the one on my Mac via MobileMe? Ok, well in the iCal preferences on the Mac it shows Sunday as the start of the week.

iCal Settings

On the Mac, the first day of the week can be set as Sunday

Ok then, well maybe because the sync goes via MobileMe then it’s something to do with the settings on my MobileMe calendar?

MobileMe Calendar settings

MobileMe also lets you start the week on a Sunday

Nope, the settings in MobileMe also show the week as starting on a Sunday. Ok, let’s have a look at the settings on the iPad itself…

iPad Calendar settings

No obvious preference setting for the start of the week on the iPad

Ah right, while I was expecting to see an option for setting which day is displayed as the start of the week, but there’s…. nothing. How strange, does Apple let you configure this on other platforms but not on the iPad? Surely not. Well in fact you can configure which day is displayed as the first day of the week in the iPad’s week and month calendar views, but you’ll never guess how it’s done. Give up yet?

Well you have to go into Settings, then select General, then scroll down to International, then finally select Region Format. Next you have to change it from United Kingdom to United States….

Hang on a minute, run that by me again. Set the Region Format on my iPad to United States?? Yup, that’s right. Unfortunately when you do that then lots of other things take on US defaults such as contact details (States, ZIP Codes, a default country of United States), also telephone number and date formats in apps etc. So despite their world class expertise in usability, it looks like Apple have dropped the ball here, and I’ll be hoping that they’ll correct this ‘feature’ in a later release of iOS.

Getting ADSL to your Airport Extreme

Apple is famed for it’s “it just works” technology, and for the most part that’s true. However, when it comes to the Apple Airport Extreme Base Station, it’s lack of a built-in DSL modem means you have a little figuring out to do if you want to use the Airport Extreme as part of an ‘internet connected’ network.

When my Netgear DGN2000 DSL wireless router expired a short time ago I decided to replace it with a Linksys WAG120N DSL wireless router. Great little device (so far) but it’s one drawback is that unlike the Airport Express which has three Gigabit Ethernet ports (1,000Mbps), the Linksys only has Fast Ethernet ports (100Mbps). Now I do large backups every day to two Synology NAS devices and they, like my Mac Pro are equipped with Gigabit Ethernet ports. Connecting them via the Linksys alone would just create a bottleneck and slow down my data transfers ten fold! Enter the Airport Extreme – the objective is to use the Airport Extreme as the centre of my wired network, but to also have internet access at the same time. Sure, I’m lucky enough to have two ethernet ports on the Mac Pro so I could connect one to the Airport Extreme and the other to the Linksys, but that’s messy plus not all Macs have two network ports. At it’s simplest, what I wanted was this…

AE Config 00

Basic Network Configuration

The first step is to set up the Linksys DSL router as normal, so connect the Mac to it via a cable and log in to it as per the manufacturers instructions. Give the DSL router your ISP details and configure it with an IP address of 192.168.1.1 and a subnet mask of 255.255.255.0. Next it’s a case of configuring the network settings on your Mac to talk directly to the DSL router, so enter System Preferences, choose Network and make sure that your Mac has an IP address (e.g. 192.168.1.4) on the same subnet as the DSL router, and tell it that the router it should talk to is at address 192.168.1.1. At this point you should have a simple network of your Mac and the DSL router and you should be able to surf the internet. Next I connected an ethernet cable to one of the Linksys routers four ports with the other end going to the ‘WAN” port on the Airport Extreme. Now it was a case of firing up the Airport Utility and manually configuring the Airport Extreme.

AE Config 05

Connect your Airport to your modem/router

In the Airport Utility, once it finds your Airport Extreme Base Station, highlight it and click on the Manual Setup button. Now click on the Ethernet tab at the top ans select Internet Connection. You should set Connect Using to Ethernet, and Connection Sharing to Off (Bridge Mode).

AE Config 01

Internet Connection settings

Now click on the TCP/IP button and choose to configure IPv4 Manually. Now it’s time to gve the Airport Extreme an IP address and tell it how to talk to the outside world.

Give the Airport Extreme an IP address of 192.168.1.2 and a subnet mask of 255.255.255.0 (same as the Linksys). For the Router entry, enter the address of the Linksys, i.e. 192.168.1.1, and for the DNS Server(s) do the same. Here you are telling the Airport Extreme that any traffic that is not for something on your home/local network (e.g. internet traffic), send it to the Linksys router.

AE Config 02

TCP/IP settings

At this point you should be able to save the settings and apply them to your Airport Extreme. The next step is to disconnect the network cable from your Mac to the DSL router, and instead connect the Mac directly to one of the ethernet ports on your Airport Extreme. Now you should find that you can still surf the web but your Mac is only connected to your Airport Extreme. You can then add devices (in my case the two NAS boxes) directly to the Airport Extreme so that they can talk to your Mac at gigabit speeds, rather than just the ‘fast’ speeds of the DSL router.

If you want to use a service like OpenDNS then there’s no reason why you can’t and it’s simply a case of adding the IP addresses of the two OpenDNS servers to your Network settings on your Mac, like so:

AE Config 03

OpenDNS settings on the Mac

I have since extended this setup with wireless and I currently have an XBox 360, a PS 3 Slim, a Nintendo Wii, a Mac Mini, an iPad WiFi and iPhone 3G, plus my Panasonic Viera TV all talking to the internet via this little network. The Linksys DSL router is currently providing the (802.11n) wireless service, but I’m looking at ways to use the Airport Extreme’s ability to provide 5Ghz wirelss to enhance this setup (i.e. avoid interference from my neighbours on the 2.4Ghz band).

QuickBitz – Windows, Minis, iDefrag & Adobe

I’m not usually one for an outpouring of comments about the way of the world, probably because the internet is already rich with folk who can express their opinions much better than I. Nevertheless, I do encounter ‘oddities’ on my computing travels, and have assembled a few quickies below for posterity.

Aperture 3 – What, no Windows version?!

I was idly browsing through PC Magazine the other day, a magazine that often covers Mac hardware and Aperture 3software. Within its pages I found a review of Apple’s latest and greatest photo offering – Aperture 3. The reviewer was very complimentary about the product, but in the final reckoning marked it down because… there is no Windows version. No Windows version of a Mac  OS X product? Shock horror. Of course the magazine often hands out five star ratings to Windows software without knocking off a point because “there’s no Mac OS X version”. Good to know that double standards are alive and well, and talking of double standards…

New ‘Mid-2010’ Mac Mini pricing in the UK

Mac mini 2010The svelte new all aluminium (that’s ‘aluminum’ for my US friends) Mac Mini can be yours for just $699 plus sales tax (on average 5%). Here in the UK that translates to a base price of £475 , which with good old Value Added Tax (VAT) at 17.5% would come to £558 . But check that price in the UK Apple Store… £649. Ouch, I hope the extra £91 is going to a good cause.

iDefrag – Great but… unneccessary?

My early 2008 Mac Pro that shipped with Leopard 10.5 has only ever been rebuilt once and that was to do a clean install of Snow Leopard 10.6. So for however long I have been messing with hundreds of thousands, if not millions of files on my four internal 1.5Tb drives. So how badly fragmented do you suppose my boot drive was when I asked iDefrag to take a look? Well the Volume Contents showed 0.2% fragmentation, and the Volume Catalogue showed 0.0% fragmentation! So then… not an awful lot for iDefrag to actually do?

Adobe, Apple and that whole Flash thing

I watched the Steve Jobs interview on D8 and I read various commentaries (from both sides) about Apple’s decision to exclude Flash from the supported technologies on the iPad/iPhone. You can probably see where my sentiments lie if I give you this analogy…

A large motor manufacturer in the US decides to launch a new model of car, and they choose to make it an electric car. The largest oil company in the US then publicly complains that the car manufacturer won’t support the use of their fossil fuel in this new car. They argue that fossil fuel allows car users to enjoy seeing a great many parts of the world, and that there’s a huge infrastructure supporting the use of fossil fuel, so really this is unfair. The car manufacturer on the other hand says that it’s their choice to make an electric car, and that they’re just trying to make the best car experience they can for those that want to buy it.

Well that’s my way of looking at it…  😉
