I'm willing to bet that it won't work. The reason:Please don't kill me if this doesn't work on a rogers/fido sim card but it does work with cingular/att sim cards in the US.
Can someone try this and post back. My phone hasn't arrived yet and I'm very interested in knowing if it works.
Cingular has been bought and rebranded as AT&T in the US. So therefore Cingular and AT&T phones (except the iPhone) at pretty much the same thing in the US. This would be the equivalent of taking a Rogers phone and using it on FIDO (or vice versa). Not unlocking it for any carrier, but merely allowing all variations of the same service to access the phone.hacktheiphone.com said:This does NOT unlock the iPhone after doing this, it still remains carrier dependent. But you can now use any existing AT&T or Cingular pre-paid account
It's also noticeable because they don't say that they can get T-Mobile SIM cards working - if they could, it would be a full unlock.
