How did you check that you're in DFU mode? DFU mode means to have a black screen. If you see any logo, you're not in DFU mode.

Greenpois0n isn't compatible with 4.2.1 on the 3G. Use the latest redsnow for untethered JB

Just google it, you should be able to find quite a few guides, if it helps, redsnow is made by the iPhone dev team

Iphone 3g is jailbroken for life, therefore you don't need GP. Just use limera1n or redsn0w to jailbreak.
