    Hi,

    I am running an jailbreaked/unlocked 3GS still with OS 4.0.1. I need to keep the unlock, but would like to upgrade to any of the newer OS versions, preferably 4.2.1, of course.

    Can this be done? Jailbreaking seems relatively easy, but the only unlock guides I seem to find are for the iPhone 4. I have also seen some articles about using the iPad baseband, which seems to kill the GPS. Is that still the case?

    My baseband is 05.13.04. I only have access to a Windows machine.

    Thanks for help!

    What you want to do is use an ipsw from pwnage tool for 4.2. This will keep your baseband which you said is unlocked right. Unfortunately it only works for Macs but I'd be happy to make it for you. Just shoot me an email rwilliams0926@gmail.com with your phone model, current firmware, current baseband. Then go to iClarified - Apple News and Tutorials and look at the tutorials for unlocking.
