Thread: Am I able to unlock my iPhone 3G? Any Help is Appreciated

    Default Am I able to unlock my iPhone 3G? Any Help is Appreciated
    I have an iPhone 3G with firmware 4.2.1 and baseband 6.15.00

    The current bootloader is 6.02 (which i know prevents me from downgrading my baseband as of right now)

    However I have tried everything I can think of to unlock the phone for use with T-mobile, but nothing seems to work

    So I was wondering... is it my configuration of bootloader, baseband, and firmware that are making the unlock impossible using ultrasn0w?

    Any help is greatly appreciated.

    I was using redmondpie's guide found here: (Update iPhone 3GS / 3G Baseband to 06.15.00 with PwnageTool 4.1.3 for iOS 4.2.1 Unlock [Guide] | Redmond Pie) when I originally tried to unlock the device

    Ultrasnow should fix it. If you still have problems, reinstalling the iPad 6.15 BB helped some users.

    I am going to try re-installing the bb using redsn0w this time rather than making a custom firmware package. But other than that I've tried just about everything. I have already downloaded ulstrasn0w and tried putting my sim card in. I am trying to unlock for T-mobile, but everytime I do it... It just says "searching" for about 10-15 min and then says "no service." I know that my sim card is one of the newer ones as well, so I also ruled that out. Any other suggestions?

    You have better luck in getting service if you downgrade to 4.1 fw.
