iPhone 4 sync probelm
I bought an iPhone 4 from a guy,when he gave it to me,he logged out from everything and erased everything from the phone(factory settings),after I got home,I set the phone up and everything.After few hours with wi-fi on I could see some of that guy things,like contacts,pictures.Now the question is how is that even possible after he logged out and erased everything from the phone?
PS:I am using IOS 7.1.2
