Hello and thanks for your time. I purchased a used iPhone 4s (it had iOS 6 running at the time). My first iPhone, but not my first smartphone. I met the nice lady at the local VZW store and they activated it for me, no sweat. We were both nervous, I didn't want a stolen phone and she had someone trying to get her to give up her vzw account info. Being new to iPhone, I didn't realize that she had not in fact wiped it. So I update to iOS 7 again no problems, yes I have my own iTunes account. Now reading about the benefits, I hear of iCloud... so I look into it. Well I can't sign in because too many free accounts have been activated on this iPhone. Now the phone exceeds all my former experiences with smartphones, face it, I'm hooked. BUT if I restore this phone to factory settings, will I in fact lock myself out, due to her not clearing it before she sold it?
