Hey all, first off, thanks in advance for anyone who can help. I can't get my jailbroken/unlocked iPhone 3G to recognize the tMobile network. The phone is a christmas present for the wife. It came running IOS 4.1 and the baseband is 5.14.02. I downgraded it to 3.1.3. (It was VERY slow when I jailbroke it on 4.1 and my phone is a 3Gs JB/unlocked on 3.1.3, so i figured that would be better.) Anyway, after successfully downgrading to 3.1.3, JB'ing the phone w/PwnageTool and unlocking it with the latest version of Ultrasnow (1.2?), i insert the tMobile SIM card and it just says "searching" and never finds the network. At this point when i had previously done this on my 3Gs, I was good to go. tMobile popped up and i was making calls within minutes, no problem. However, my 3Gs' baseband is 5.12.01, so I'm assuming that's the difference. I've tried downgrading the baseband, but my bootloader is 6.02 and apparently not downgrade-able (? at least it wouldn't work using fuzzyloader.) So... I'm stuck. HELP PLEASE!!! I'd prefer to keep it running 3.1.3 and not have to upgrade it to 4.1, since it ran MUCH slower on 4.1. Also, I'm using a Macbook pro to do the jailbreak. again, thanks in advance!
