have had an Apple ID that predated iTunes. It wasn’t in the form of an email address, it was just “funpaul”.
Now that I have an iPhone 4S and am developing apps for iOS I thought I should start using iCloud. But I was getting this error
Unsupported Apple ID:
iCloud requires an Apple ID that is an email address (including @me.com addresses).
Unfortunately the Learn More button is worse than useless
