can anyone help i have.
iphone 4 4.0.2 jailbroken with limera1n.
unlocked with ultra snow.
put tmobile sim card in goes to emergency screen.
 
Did you cut the tmobile sim to micro-sim? If you did, you may want to check if you had done it properly. I had trouble in the first place, but eventually realize what I had done wrong, and get it to work.
 
i have problem, since i'm used iphone 4 1month, this morning i got signal no service, then this afternoon i got signal invalid. i'm try to clean my simcard and refresh. still like that. i cant comunicate today...pls somebody help me?
 
In my case, the card was cut too small, I had to try moving it a bit in order to get a good contact and signal. I use a scotch tape to tape it down (just a little piece is good enough). This trial and error may take a few times.
