I currently own a 4GB iphone week 32 with the 3.9 bootloader. I upgraded to firmware 1.1.4 and unlocked it with ZiPhone. It was working great up to a couple of days ago. In the corner where it use to say T-Mobile, it now says No Service.
The phone does not make or recieve calls anymore. I downgraded back to verison 1.0.2 and revirginized the baseband...still nothing.
Is there anything I can go to fix it, or is it screwed. Any help would be appreciated.
