    I'm old dummy guy... Currently have old 3GS ver 3.1.2, unlock for tmobile. My question may be an old one, but anyone PLEASE help me to show me links and how to step by step to jailbreak and unlock w/o loosing of anything that currently have (gps, $10 unlimited and tether Internet). Any version that is 4.0 or above. Btw, what is tiny umbrella?

    Thanks a lot for your kindness


    Also, I only have windows Vista.

    download sn0wbreeze from ih8sn0w's site or somewhere else on the web. this upgrades the firmware but not the baseband, the part of the iPhone that is crucial for the unlock. to do this you'll need to download a 4.3.3 stock firmware, once again, google is you're friend. and just follow the steps that sn0wbreeze says to do and you'll be good, give it a go and let us know how it goes

    +1. You won't lose GPS this way and your internet isn't affected by firmware updates of any sort.
