Hi everyone.
I have a 3GS with stock firmware 4.2.1 installed, and deactivated (after full reset).
I want to JB and install 4.3.3 firmware.
I found many tutorials how to use snowbreeze to make custom 4.3.3 firmware from original and then restore it in iTunes. But would it work in this case, as I have the Apple FW 4.2.1 installed? Are there any better solutions?
It's not important to preserve baseband, as it's not supported by ultrasnow and can't be unlocked.
