before i start, the iPad with the login issues is running 4.2.1 and is jailbroken. i jailbroke it using RedSn0w on my MBP. So on my gf's iPad, she is logged into her account; her email, info, everything. but when she tries to download anything from the app store, it keeps asking for my login info. no matter how many times she logs out and logs back in, it continues to ask for my login info. even tried it with her iPad plugged in to her MB. i dont think it is due to the jailbreak, but it's just strange it will never show the correct info when downloading from the app store. anyway, i figure i can just backup then restore back to 4.2.1 and rejailbreak on her MB, but im trying to avoid it because customizing the iPad the way she wants it is a tedious process.
