1. Error Messages
When updating, most individuals received an error message after backing up. In the beginning, this was due to a system overload, however there is still a possibility that you could encounter this problem even today. I personally encountered an error message four times before finally getting my hands on the software. The simple solution to error messages is to try and try again. Persistence is key because error messages hit random individuals, not necessarily due to your device.
2. Network Issues
If you encounter a network problem, then we would like to say congratulations on successfully getting iOS 5 on your device. Don’t worry, a network issue is quite simple to fix and can be resolved without even connecting to iTunes.First, you’ll have to go to “Settings -> General -> Reset -> Reset Network Settings”. The “reset” page scares many, especially since a couple of wrong moves can wipe clean your device if you don’t know what you’re doing. However, resetting network settings simply put your device’s carrier settings to the factory default. The worst that happens is that your saved web passwords are lost, another reason to keep better track of those pass codes!
3. Slower Device
Despite Apple approving a device as iOS 5 ready, that doesn’t necessarily mean it will run as well as on the iPhone 4S for example. Devices like the iPhone 3GS, especially the 8GB model, can run a little slower with iOS 5, even with a standard amount of applications. I personally run iOS 5 on a 3GS. I find it to work fine with average iOS 5 specific tasks, but can be buggy when going to features like Notification Center while using more processor intensive activities like games.
4. Device Just Won’t Upgrade
Some users forget that iOS 5 just isn’t available for all Apple devices. This is due to system requirements that older devices don’t support. Usually when the most recent software doesn’t support a device, that’s usually the sign that the device is considered discontinued and you should look into an upgrade. For iOS 5, these are the devices supported:
iPhone 3GS iPhone 4 iPhone 4S iPad Original iPad 2 iPod Touch (3rd and 4th Generation)
In addition to your device, make sure you have the latest iTunes software. There was an update that was released before iOS 5 was released to prepare the system.
When All Else Fails
If it seems like there is no solution to this problem, don’t worry, there is always another way. In this case, it does involve a full reboot of your Apple device. First, back up your device. Since backing up doesn’t involve iOS 5 in any way, it should back up without a problem.
Once backed up, reset your device within your device. This is done by going to “Settings”, then “General”, followed by “reset”, and finally “Erase All Content and Settings”. This process can take one to a couple of hours, so do other things while you wait.
Once done, update as if it were a new device and your problem should be fixed.
If not, it’s definitely an internal problem that may be beyond repair. Apple Care should provide you with a new device due to the fact that it’s an internal problem; all you will have to do afterward is perform a simple sync. Your new iPhone should come automatically with iOS 5. This also means that you could do OTA (over the air) sync and set up from the iPhone itself.
