Having problems upgrading to iOS 5 on your iPad or iPhone? You could be one of the estimated one in every thousand users who is experiencing problems.The most frequent problem when upgrading to iOS 5 is an error message ambiguously entitled “Error 3200.”The Apple store geniuses at the genius bar only say that this error is something they’re working on, and add that there is nothing we can do to change that error code.Cause of the problemThe problem is occurring because there are too many people trying to access Apple’s servers at the same time. The problems should all have been resolved within the next 24 hours.The problem starts when your device tries to contact Apple servers for authorization. When the Apple servers were being accessed by millions of users trying to upgrade to iOS 5, many of the requests were not being fulfilled. As a result, many users are reporting trying over again, where the Error 3200 mysteriously disappears.So one way to solve the problem is just to keep trying. Since Apple’s servers are said to only be fulfilling about half the requests, you can easily win the coin-flip and get authorization.Other problems reported:

• Having to reorganize all your apps - it is an unfortunate time-consuming exercise, but only seems to affect users who have upgraded from a previously not up to date version of iOS (4.3.2 or before)
• Backup taking a long time.
• Downloading the upgrade taking a long time. It’s more than 700 MB, and because the servers are so overburdened, it’s taking longer than usual.
• Inability to register for iCloud.

On the positive side, most users are saying the process has been seamless — even though most find it takes a long time to download iOS 5. Some report downloading the update in 15 minutes on broadband and in less than 2 minutes on a fibre connection. But after that, there is an extra backup process that takes much longer than usual.
