I've had my IPhone since mid-November. Early-on when it was running 1.1.1 I went thru the whole Jailbreak routine and was able to use the SIM from my pay-as-you-go Sony-Ericcson T68i without any problem. Then I, foolishly, upgraded to 1.1.2 and the applications and the ability to use the Cingular SIM went away.
I tried several times to downgrade to 1.1.1, but it never worked. The closest I got was to be able to load third party applications, but the the phone would not recognize any SIM. I finally did a total restore back to 1.1.2 and everything was back to "normal"
Today, I saw the extensive procedure posted by iclarified.com and said, "what the heck", I'll give it another shot. I was all set to start, when I decided to look at baseline performance and swap SIM's between the IPhone and the T68i. The AT&T SIM worked in the T68i, as expected, but, amazingly, the Cingular SIM worked perfectly in the IPhone.
This is one of the first things that I checked when I did the restoration back to 1.1.2. The Cingular SIM did not work at that time.
Can anybody tell me what's going on here?
After I posted this thread, I synched the IPhone with Itunes and everything worked fine, except, I tunes still thinks that the phone has has the AT&T phone number event though the Iphone itself shows the Cingular number - stranger and stranger.....
