Hi guys, I am using an old iPhone 3G which I am trying to jailbreak using GreenPois0n RC5. I have already restored my iPhone to iOS 4.2.1 and installed the latest version of iTunes. So I connected my iPhone to my computer and followed the on-screen instructions very carefully. However, it seems like GreenPois0n is not detecting my iPhone in DFU mode. I am pretty much sure that I have put my iPhone to DFU mode as I hearing it plug into my computer when I complete the DFU procedure. I am using Windows 7. If any help on this issue would be awesome! Thanks.

There are also possibilities that you have downloaded a corrupted GreenPois0n for your Windows. Also, you should use GreenPois0n RC6 instead of the RC5 version of the jailbreak tool.
Anyway, you can check this blog post to download and know more about the RC6.1 version of the GreenPois0n jailbreak tool to jailbreak iOS 4.2.1. Just to make sure, you can follow this guide (Mac OS X users can refer on this tutorial) on how to use GreenPois0n to jailbreak iOS 4.2.1 on iPhone 3G.
