    Currently my iPhone 3Gs is on iOS 5.01. I'd like to use it on the T-Mobile network. What are the steps required to make it happen?
    I think it's obvious that I need to jailbreak the phone. However, googling around around it is unclear whether there is a reliable (untethered) jailbreak for 5.0x.
    Do I need to downgrade the OS? If so, to what version and how? Any additional steps I need to take?

    Moved to iPhone Unlock.

    Unless you preserved your baseband when you updated to 5.0.1, you won't be able to unlock it. The baseband that comes with 5.0.1 is currently non-unlockable and it can't be downgraded, so you won't be able to use ultrasn0w to unlock. The GEVEY SIMs aren't compatible with 5.x basebands.

    I didn't preserve anything - just upgraded to 5.0.x.

    Let me understand this fully. Would I be able to do this with a tethered jailbreak for 5.0.x (that seems to be available)? Or is this a non-starter to begin with? Sorry, I don't fully get the baseband thing.

    Is this something I'll be able to do in the future?

    There is currently no way to unlock your iPhone for use with T-Mobile. You can jailbreak it, but you can't unlock it. There might be an unlock option in the future.

    idownloadblog has good info on jailbreaking but the other site is a paid site. You don't have to pay to unlock just read the forums here or google it or ask us here.

    Why the same post on 2 threads? I think you're account has been hijacked.
