Check what bootloader you have first with f0recast: iH8sn0w.com | Jailbreak your iPod touches and iPhones
If you have 5.8 you can downgrade baseband then unlock. Anything higher than that and the only way to unlock is to use redsnow 0.9.6rc8 to update to the ipad baseband. You will lose GPS doing this though and there is no going back.

Yeah unfortunately only the first batch of 3Gs when they originally came out had the 5.8. I think once the 3.0 fw came out is when they started loading them with the 6.4. You'll have to use the iPad baseband. Sorry

Thanks a lot bro! Now I am just gonna restore to a stock 4.2.1 and then Jailbreak with redsn0w 0.9.6rc8, installing Fuzzyband from Cydia will downgrade the Baseband to 05.13.04 from 05.15.04 because this phone has a 5.8 Bootloader, finally unlock it with repo666.ultrasn0w from Cydia. Hope I am gonna have everything working in this device after unlocking it.. please wish me luck!

So, unlockable after downgrading baseband, but no GPS due to the bootloader?

with a 3G that has the new bootloader, running 4.xx and 05.15.04 baseband is there any sim or turbo sim or what have you to unlock?
If there is could you post a link to a real site. I found one for the ultra but that says it is for Iphone 4. Thanks

Okay so u guys posted how to unlock with BL 5.8 but what about 5.8 and higher?
I downloaded :
iPhone 3G/3Gs firmware 4.1
redsn0w 0.9.6b5 for Mac or Windows
from this guide HOW TO: RedSn0w 0.9.6b5 To Unlock Your iPhone 3G/3Gs With Tricky New Ultrasn0w [Mac & Windows] | FSMdotCOM
When I try to do this step:
1. Restore your device with a stock iOS 4.2.1 firmware. ( again, by doing this you will loose the ability to unlock!!!)
Itunes can't read my iphone.
My iphone is a 3g with 4.2.1 firmware and baseband 5.15.04. It doesn't show up in itunes so i tried to redsnow it anyway with ipad stuff. It goes to loading ipad screen, then it just disappears.
Anyone have any idea?
Thanks in advance
