i got a an unlocked 3g phone frm ebay , i got it wrking on my tmobile sim until i plugged into iTunes and asked to be upgraded to the latest 3.0.01 firmware. In the process it froze to the recovery mode. I finished the recovery mode, got it jailbroken using redsnow 0.8 and unlocked using cydia. Now when i insert my tmobile sim, it just shows lines (where the bar is supposed to show up with the Tmobile word). It doesn't say invalid sim.
Please help!

Have you unlocked it with ultrasn0w, turned off 3G, and then rebooted?
