just bought a used iphone 4 on CL....and believe it or not, I didnt meet the guy at an at&t store noer did I put my sim card in it to see if it was working (my sim card was the wrong size). anyways...he had his sim card in it and was showing me the back and forth texting while negotiating...etc...I get home and do a factory reset and now I cant go online, cant even access app store....besides the stop button being a little sluggish ( I have to press it hard for the main screen to come back) I dont know what is wrong...I THINK it had been jailbroken and when i di the reset something got screwed up. when i try to erase all content and settings it asks for my apple ID and after a minute or two a banner appears out saying "verification failed" the request timed out....
