I have a 32g 3gs that is jailbroken and unlocked for Tmobile. Last night I downloaded the new pwnage tool to upgrade to the newest pwnage supported version. I was at 3.0. I made the custom firmware and restored using that. Everything went smoothly, but now it just says searching and can't make/receive calls. I checked the baseband, and somehow it upgraded the baseband with the custom firmware to 5.11.07.

Is there anything I can do? Fuzzyband tells me I can't downgrade. I do have that thing on Saurick's server, but have no idea how to go about fixing this or accessing that to possibly downgrade to 3.0. Any suggestions?
