How to fix some mysterious problems.

I have an iPhone 3G with 4.2.1 installed. I am currently jailbroken with Redsn0w. Can I use Greenpois0n to jailbreak it again? Would I have to restore it first? I tried greenpois0n and its not reading my DFU mode.

If you're already untethered on 4.2.1 with RedSn0w, there's not really much point in re-jailbeaking anyway.

Greenpois0n won't work on the 3G, as the included readme states. You could use Sn0wbreeze though.
