can you provide more information? like was it a fresh install from oficial 4.2.1? or custom or you preserved your baseband, did GP finished or gave you an error, in what state is your phone, DFU, Recovery, completely dead, eating ice cream, etc.

the computer is telling me it is in DFU mode. i downloaded green poison and i followed the directions for holding the buttons, then it just turned off and i can't turn it back on. Was i supposed to download something else first. Please help me, i'm not that computer literate at all.

you need to make sure the latest itunes version is installed, also make sure your firewall/antivirus is not blocking the internet access to GP (greenpois0n) since it downloads files from a server, after you are on DFU and you have the requirements you should be able to press Jailbreak on GP, also if you are using windows vista or 7 make sure you run GP as administrator.

Just hold the home and power buttons at the same time until you see the apple logo. It can take 30 seconds or more sometimes. This will kick your device out of DFU mode which it sounds like you are stuck in at the moment.
