I have a 16GB iPhone 3G [S] on firmware 3.1.3, baseband 05.13.04 as I was running iOS4 until blacksn0w was updated and I downgraded back to 3.1.3 for an untethered jailbreak and unlock. It's now unlocked, I have signal, but cannot send messages or make calls, they just fail instantly. 3G is disabled in the settings menu, and I've rebooted a few times now.. I have a Virgin mobile contract sim card.
Does anyone have any ideas what the problem could be and how to solve it?
I've tried restoring 3.1.3 and unlocking again, still doesn't work. The sim says activated when I put it in, but still no calls or texts.
