yay, managed to recover the long lost source code to redsn0w :) ..will port it to 3.1.2FW if there's any interest (mac+win+linux)
Redsn0w is an easy to use, multi-platform, multi-device jailbreaking and unlocking tool for the iPhone 2G (original iPhone), the iPhone 3G/3GS and also the iPod touch (first and second generation). It is available for Linux, Mac OS X and Windows but has not been updated for the latest firmware.
*Update: Looks like Redsn0w will be updated and get a new boot logo feature. Take a look at the screenshot below...
*Update 2: Seems PwnageTool will be ported to Windows and Linux as well.
