Cant send nor receive text/MMS after upgrading to 5.0.1

[PinoySaMI]

I upgraded my jailbreak/unlock 3GS to 5.0.1 and 06.15.00 firmware and now I cannot send nor receive text/MMS.

I tried everything from Sinfuliphone text/MMS fix to different input in the Cellular Data Network but nothing works.

I am at lost of what to do!

HELP!!!

Did you eject and reinsert sim?

Yes. I've tried that. I even put an active AT&T sim card and still did not work.
