I have a used iPhone 4 I bought off of amazon not too long ago. Its been working fine for a couple weeks. Then I jailbroke for another couple weeks. Now I restored because I was having some network errors and I figured it was the phone being jailbroken and what not. So now that its restored, I'm getting the regular pop-up to restore via iCloud so I need to enter my Apple ID, however an unknown email address is already in the email address bar waiting for me to enter the password, so each time I have to delete and enter MY apple ID. ?? It wasn't like this before the jailbreak. Any advice? This is about the 3rd time the phone has been restored since getting it from Amazon, how can it still have (i'm assuming) a past users info??
