So I tried to jailbreak my brother's iPhone 4 (Verizon) using Jailbreakme.com It installed Cydia, but then locked up. I then realized that his software only goes up to 4.2.x and Jailbreakme.com works on 4.3. (I could be wrong about all that above) Anyway, I froze his iPhone. I had to do a total restore via iTunes. Now here is the part where I am having a problem. The iTunes and Mac I restored it on also shares iPhone accounts with two other people. Miraculously, after restoring my brother's iPhone, I simply restored his information from a backup. All his contacts and emails were restored. But here is the problem.... Somehow....his iTunes account is now under my email address. That means, when he goes to buy an app from the Appstore, it comes up with my email address and calls for my password. Is there any way of restoring his original account to iTunes while keeping all his individual data intact? Thanks for the help.
