hey guys ive unlocked a 3g before but now i got a newer it seems 3GS. ive been reading stuff thats saying after serial number 135 you cant do it. so any tips would be appreciated my goal is a UNTETHERED unlock. like turning off phone sometimes . thanks guys. Serial - 86143xxxxxxx firmware - 05.15.05 verison - 5.0.1
Untether using the latest redsn0w. To unlock it you would have to install the iPad baseband, which is known to break GPS and compass.
I haven't updated my thread, as I haven't had time to go through and fix it all but it is basically the same thing. If you get lost, I can help explain it more updated. Did update the link to sn0wbreeze for 5.1 though. http://www.ifans.com/forums/threads/important-guide-for-iphone-3gs-unlock.369105/

When jailbroken, open Cydia and install ultrasn0w to be unlocked. [DISCLAIMER]Compass and GPS will likely NOT work if you do this. You will also have to restore to a special firmware every time you upgrade. You have been warned.
Theres a chance you will brick the phone. As Kona said: The compass will probably work. GPS- not a chance. The special firmware thing is also annoying- if you use the Update button in iTunes, congratulations! You just bricked your iPhone's baseband! Activation will be impossible unless you reflash the iPad baseband. Flashing the iPad baseband a second time can easily brick your iPhone permenantly (it didnt happen to me, but its possible). So to sum that all up:
