So I've been living in the states for the last few years and bought the first generation iPhone when it came out (the one that was on the EDGE network and was only available in the US) and I'm moving to Ontario and have a cell phone plan with Rogers already and I'm trying to figure out a way to use my iPhone with my Rogers plan.

Do I have to unlock or Jailbreak my iPhone somehow? I tried just putting in my sim card from my current Rogers phone and it didn't like that too much.

Also, if I DO unlock or Jailbreak my iPhone, is it possible to restore it back to a previous backup and un-Jailbreak it or un-unlock it?


Thanks in advance for your answers.
