I will be buying an iPhone from someone off of Craigslist tomorrow, He said in his Ad "This is not hacked but it does work without service because of a contract cancellation loophole I used. Will work with any AT&T SIM Card." Well, i do not have a contract with AT&T and do not have a AT&T sim card. But do have a t-mobile contract and a t-mobile sim card. Can i still unlock this iPhone like normal through ZiPhone by using the "Do it all" feature and then use it with t-mobile?
Thank You
