I have an iPhone 3G from Rogers. It's been jailbroken and unlocked (or so I thought) for the past year, but I wasn't using it since I was in Korea. Anyway, I got a Fido SIM today and popped it in, no go. Under About, Network, it says 'Not Available'. I turned 3G on and off, still nothing. So I fully restored it with a jailbroken version of 3.1.2 (don't really care about 3.1.3), and used blackra1n to unlock it. Same result. I'm beyond frustrated because I haven't been able to use my iPhone for the 2 years I was in Korea, and now I'm still not able to! So, my question is, can I restore it to the locked firmware, which is locked to Rogers, and still use the Fido SIM? Rogers and Fido are the same company. Any help would be greatly appreciated.
