I bought my iphone 8 gb from a freind whos cingular contract was cancelled. But am using t-mobile (The DASH rocks but not better than the Iphone) so i need help unlocking the iphone so i can use my cingular sim card. I have been reseraching online and am hearing stuff like rebooting, addware, ams, andi have no idea what that **** means,..... CAn someone pls step by step explain to me what to do.... I know this much it is a version 1.1.2 am not sure weather is OBT .... but all i really want to do is to be able to use the iphone with my t-mobile servies, still use the you-tube, and my t-zones plus my fav 5,
