Need to be running 4.2.1 but before you go updating to it via itunes, what are your service/unlock needs, if any?, you may want to keep that 1.59.xx baseband that you should have.

Do you have access to a Mac, if so go here and use Pwnage. I expect Sn0wbreeze will also preserve baseband, but I have zero experience of it.

Yep, just double check that it preserves the baseband, if it works like Pwnage then you should be able to build a custom 4.2.1 firmware that keeps the baseband update blocked, either by default or user selection. I'm sure someone else knows more than I can tell you about Sn0wbreeze.

GP works on iOS 4.2.1 or 4.2.6, not 4.0.2

From the GP readme:

Requirements (check this !)

  • a supported device (see above)
  • the device should run iOS 4.2.1 (4.2.6 for iPhone 4 Verizon). Please check on the device in the Settings -> General -> About page. If your device is running an older version, please upgrade iOS first using iTunes.
