Looks like Apple are struggling to keep up with demand for iOS 5 updates today!

If you’re receiving the message “internal error” or “3200”, it’s due to Apple’s servers not coping with the demand.

In fact error 3200 is now trending on Twitter as so many people are reporting the problem.

You can keep re-trying the update and maybe get through, or wait until later when things have calmed down a bit.

Don’t forget – run a backup before updating as some people are reporting lost apps having updated today.
