There's an easy new program you can use to jailbreak the iPod Touch, called iJailBreak. You can download the installer (which now includes both PowerPC and Intel mac support) at code.google.com. Sorry, no Windows love yet. iJailbreak makes "heavy use" of the iPod Touch / iPhone TIFF vulnerability, and its use requires that you only restart your iPod Touch. Simple enough, right? Way simpler than this, anyway. iJailbreak is programmed by a 13-year-old, and judging from the broken tabs at the top right of their website, they have an unbricker application planned.
