To unblock my new iPad 2, the IT guy from work entered his iTunes account details. This was because I couldn't get iTunes to work properly on Windows 7 Home Premium (I still can't - it keeps giving error 9808).
I now want open an iTunes account in my name on my iPad 2, but it keeps asking me for other other guy's password. I have an iPad 2 general user's account with correct details and password, but it doesn't show on iTunes.
How can I cancel the old account and enter the correct details?
Tap on the currently logged in id in Settings > Store and then log in with your account. If he downloaded any content to your iPad then that content will be tied to his account
