Since finding a no commiment iP4 is near impossible right now im thinking of snagging one off of eBay. Now lets say i buy one that has no contract to it. Once i recieve the phone (thats been activated but sim removed) How do i get the sim in my 3GS into a MicroSim that i can pop into the iP4 and use it like a no commiment iPhone? Anyone know if theres a way to do this? Im sure there is as a bunch of people are buying these phones off of eBay. Many Thanks!
