    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

    Yup, no other way to unlock that unfortunately. Unless it is locked to a carrier that is willing to officially unlock it for you.

    I am also stuck on 4.2.1 Baseband 05.15.04, but as a matter of joy I have the 5.8 BL. So I am wondering what should be the proper steps of unlocking my device without losing the GPS or anything else. Could you please help me with this process? Thanks so much.

    Look for fuzzyband downgrader in cydia. That will downgrade your baseband to an unlockable one.

    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?

    Huh? His gps should be just fine since he doesn't have to use the iPad baseband method.

    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
    iTunes 10.1
    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

    The stop in redsnow was "fetching ipad baseband files" then it disappears

    Hey bro, sorry for the delay to update you regarding my problem as I got stuck in some other important work. But I am back on the unlocking process, and just to let you know.. it's been a miserable experience with this phone so far :@. Lemme tell you some of it. With a stock 4.2.1 I could not jailbreak it using redsn0w0.9.9b7/redsn0w0.9.6b8/redsn0w0.9.6b5 and not even greenpois0nRC6.1 because the phone(it's an old phone btw) won't go into the regular(3s power>10s power+home>15s home) DFU mode! Then I figured it gets into the pwned(10s power+home>15s home) DFU mode. So I decided to try sn0wbreeze and created a custom IPSW using sn0wbreeze-2.2.1. That way I was able to jailbreak and get Cydia on it. Then I updated Cydia and loaded Fuzzyband 4.1 but it doesn't seem to work! Please do lemme know if there is any other ways I should try to unlock this device, I am still not willing to update to the iPad baseband. Oh and I am wondering what might happen if I update the BB to 06.15, then downgrade it to 05.13 and then unlock it? That way I am still going to lose the GPS as 06.15 is an iPad bb, right?
