Finally! As promised, iPhone Dev-Team has released Ultrasn0w (v1.2) tool to unlock iOS 4.1/4.2.1 on iPhone 3GS and iPhone 3G. Ultrasn0w 1.2 can unlock 01.59.00 baseband on iPhone 4 and iPhone 3GS/3G basebands 04.26.08, 05.11.07, 05.12.01, 05.13.04 and 06.15.00.
Unlock 05.14.xx & 05.15.xx Basebands with Ultrasn0w:
If your iPhone 3G/3GS has 05.14.xx or 05.15.xx baseband, you can still unlock your device by first upgrading your baseband to 06.15.00 and then using Ultrasn0w 1.2 for the unlock. Download PwnageTool 4.1.3 from here and follow the step-by-step guide here to upgrade your iPhone 3GS/3G baseband to 06.15.00. Once done, skip the jailbreak methods below and jump straight to the unlock guide after the break.
Update: Instead of using PwnageTool 4.1.3, use Redsn0w 0.9.6b5 to update iPhone 3G/3GS baseband from 05.14/05.15 to 06.15.00. It don't require you to download iPad iOS 3.2.2 IPSW plus its available for both Windows and Mac OS X users.

What is your BB, iOS & iPhone model details? Please spend time in making your query much more detailed with the necessary details as its very difficult for us to make guesses.
thank you very much, love this thread, very helpfull, it,s work,!!!
lol..
MAn! this rlly!! works!! thanks alot!! GPS is not important.. xDD
Works like a charm. Go to http://bit.ly/puOynD to jailbreak your iphone and then follow the instruction here to unlock.
Works well for iphone 3G.
I used limera1n to jailbreak and ultrasn0w to unlock but my 3Gs cant find service, it is on the 4.1 and 05.14.02, 3G is turned off too, im trying to connect to tmobile. What’s the deal, any ideas?
Ultrasn0w can never unlock your iPhone 3GS baseband 05.14.02 directly. You need to upgrade your baseband to iPad baseband using this guide http://bit.ly/gI22Px and then unlock with Ultrasn0w 1.2.1 http://bit.ly/i7A1MD
My current Carrier doesn’t allow me (yet) to access 3G, I have to live with Edge. But I prefer that (coupled with Wifi sometimes) rather than loosing my GPS. I think I’m fortunate enough when I decided to stay away from this unlock method. Sadly, some guys were trapped when crossing the point of no return of this method.
Then the real queestion is: Remain Locked Forever or Loose your GPS Forever!
Lose GPS or use your iPhone as an iPod for the rest of your life.
Is Turbo sim an option here?
Gevey SIM is only for iPhone 4. In past, TurboSIMs were used to unlock iPhone 2G.
What about the GPS bug with the iphone 3g and 3gs? Is it fixed?
It is not a bug. iPad baseband do not (will not) support GPS ever!
