help :D 6.1.2 no service error (jailbreak related)

i updated my 04.26.08 baseband iphone from some very old 3.x jailbroken version to 6.1.2 using sn0wbreeze (i have cydia and i made sure to hacktivate it) But the weird part is when I plug in my tmobile sim I am stuck on NO SERVICE now. Wut do?

by the way when i connect my iphone to my computer and run redsnow it says I am on 6.1.2 with 04.26.08 for my baseband.

i even tried clicking reset network settings on my iphone and still no service ;_; btw this is one of the first iphone 3gs's.

You install ultrasnow?
Is it compatible with iOS 6.1.2 yet in order to unlock?

I fixed it by going into cydia and installing ultrasn0w.

it just worked, the second I installed it boom I had service.

I love you all. <3
