To easily upgrade your baseband to 06.15.00, re-jailbreak your iPhone with redsn0w (iOS 4.xx) while selecting Install iPad Baseband. There is a chance to lose GPS though. After that, you can unlock it with ultrasn0w.

Did you try to upgrade to 6.15? If so, did you lose GPS? I am really tempted to try this out, but the main reason I want to unlock it is to use the gps while I am over in Europe, so will kind of defeat the purpose if it definitely breaks it.
Yes, it has been unlocked and the base band is 6.15.
Can anyone help me out to connect Wi-fi. I am unable to connect Wi-fi.
