So my uncles friends son or whatever got a job at a compony that doesntlet him have an iphone he must use a blackberry so he is giving it to me. He took out the SIM card and tossed it he said. idk if he reset the iphone or not. I am not a current AT&T customer but i plan on switching from verizon if i can use the iphone i am getting. question is can i use it since it has been activated before? ive looked around and gotten mixed results things from i need the original SIM card when i reset it or if it is reset itcant be used some say it doesnt matter AT&T can just make it work. So whats the truth
