I have tried every major unlock and jailbreak program out there and it all has the same results. Sure i can download and install programs as well as use all the features. Except for one MAJOR FLAW.
When the iPhone starts up i receive a signal but after maybe 30 seconds, the signal disappears and says no service, then after a few seconds the message "No Sim Card Installed" and finally No Sim.
I am running 1.1.4, or at least trying to. I thought it might be because the phone is locked. But apparently the major jailbreak programs unlock the phone already.

There is absolutely nothing wrong with the sim card.
