Desperately need help

[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!!!

I heard of a guy who Jailbroke his 3GS, effed it up with some updates then could never connect to any carrier ever again because the cellular firmware in the phone was effed. Jailbreaking comes with a risk.
