    Default can I unlock and jailbreak 3gs,4.2.1, firmware 5.15.04
    can I unlock and jailbreak 3gs,4.2.1, firmware 5.15.04?? I want to use on tmobile and can't find a guide anywhere. don't have to stay on 4.2.1 would upgrade and do whatever but would like to preserve the baseband.

    I've only read that i would have to use the ipad baseband and would then be stuck for any future upgrades. Can you please point me in the right direction to do this it's my daughters phone and it's just been sitting for months.

    You can use redsnow to jailbreak and update your baseband if you want. Ne aware you will lose gps doing it though.

    Yes, gps does not work right after installing the iPad baseband. Any navigation app like Tom Tom will not work properly.
