Have an old iPhone 3G. Did a jailbreakme.com followed by ulrasn0w 1.1-1 to unlock today. I have a 2 year old SIM from Europe (Lebara prepaid mobile). I wanted to test if the phone was really unlocked. I popped in the SIM, and was asked for the unlock code. I typed the code, it accepted it. (Is this enough to prove that the phone is unlocked?) But then i got the "waiting for activation" screen. It never activates. I have no service listed. If i go into settings, I now have an option for carrier (See picture). Is this proof that the phone is unlocked? If I select carrier, I get two options: AT&T and T-Mobile. (See picture) Is this proof that the phone is unlocked? So is my phone unlocked? Is it possible the SIM is old or dead so it doesn't work here in the US anymore? I don't have easy access to a t-mobile SIM, and am afraid to pop in my old AT&T sim or else AT&T may know something is up.
