The iPhone Dev Team released a new version for their iPhone homebrew app collection, Windows QuickPwn 2.1. This new version supports the 2.1 firmware with the unlocking and jailbreaking of iPhone 3G (2G) device.

Apart from that, it also supports the jailbreaking of iPod Touch 1st generation device and iPhone 3G. You will need upgrade your device, though, to 2.1 through the use of iTunes 8 before you can successfully run this application.

Here's the changelog:

• Support for firmware 2.1
• Auto-detection of firmware version, insistence on correct firmware bundle to prevent user epic fail.
• Use of iASign to activate to prevent bspatch epic fail.
• Removed buggy and never really tested 2.0 support

However, it does have its limitations, which are the following:

• It does NOT support the unlocking of iPhone 3G 
• It does NOT support the jailbreaking of second generation iPod Touch introduced last week
