Ive tried to activate 3 different iCloud accounts from my iPad (iOS 5 GM) trying the Mail to get work - http://forums.macrumors.com/showthread.php?p=13481717 And I seem to have hit a wall. No more accounts can be added. My iPad says: "The maximum number of free accounts have been activated on this iPad". I did not see any documentation limiting the number of accounts I could setup from my iPad. Does Apple limit your device by serial number, track it? Is there any way to remove an account from a serial number? And what if I want to sell my device, new owner also wont be able to add new account?
