I followed the instructions on this page: http://www.simonblog.com/2011/02/07/how-to-untethered-jailbreak-iphone-4-or-3gs-on-ios-4-2-1-for-windows-user/

In an attempt to jailbreak my i-phone 3G running 4.2.1. Now, after Greenpoison failed the phone will not start. Can anybody help me to get this working again because I've only just paid for the phone and I'm screwed if it's bricked!

Thanks everyone, I hope you can help me.

um you might be in dfu mode so hold home button for 15 seconds and then hold home and lock button for 10 seconds and then only hold lock button for 2-3 seconds.

You cannot brick it.

With "won't turn on", do you mean the Apple logo? In this case, just run greenpois0n rc5 again - it should get you out of this recovery loop. more infos

In case everything fails, you can always do a fresh restore in iTunes. Put your device into DFU mode and install 4.2.1 again. Then rerun the latest version of greenpois0n rc5 to jailbreak.

could be a hardware problem, check your doc connector or if your device is more than two years old, the battery could be dead.

iPhone 3G 4.2.1 jailbreak tools are: redsn0w, sn0wbreeze, and probably pwnage tool (if mac) but never greenpois0n. Restore and start over. Use a custom ipsw if you need to protect/preserve your baseband for present or future unlocking.
