Hey guys Ive gotten IPad sim working with apn changer before, the sim was an AT&T sim. now im traveling at Canada for the winter and I want to get a sim from a local carrier ( eg Rogers). In this case does my phone need to be jail broken? I'm running on iOS 5.0.1 so chance for me to jb is verry slim. Im trying to figure out a way to use my phone here.. Maybe a certain prepaid plan would work?
