Firmware 04.26.08 and iOS 3.1.2. Upgrading to 4.2

[sepandee]

I have the iPhone 3G on baseband 04.26.08 and iOS 3.1.2. It's already unlocked and jailbroke. I want to upgrade to 4.2 but not sure which instructions to follow. Do I keep my baseband firmware the same? If so, how? Or Do I upgrade it to something else?

Thanks a lot.

You'll need to create a custom 4.2.1 firmware in PwnageTool or download one to upgrade.
