How to access my iPhone4?
I erased all my contacts from my iPhone4 and it ask. What my Apple id was? I provided my Apple id by doing so it get shutdown and then automatically restart. When it got restarted then again it was asking for my Apple id but this time it pops up a message that "Incorrect Apple ID or Password". Now what should I do to get my iPhone back.
Note: I have purchase it from my friend.
iPhone 4, iOS 7
