Moved here to Canada Vancouver for a work VISA (YAY vfx industry) Have an iphone 4 jailbroken and im going to install unltrasnow on it Currently I have ATT and I was told that Rogers has the same 3G baseband and GSM fallback for edge. It also roams on Rogers when here. There is this other company called FIDO that has better deals. I was wondering if they use the same things as Rogers cause they are owned by them? Same tech. Can I unlock and use a FIDO sim and have it work? Thanks!!
