George Hotz, the 20-year old hacker who originally unlocked the iPhone, has released a jailbreaking application for the iPhone 3GS codenamed “purplera1n.” It’s currently Windows-only (Windows 7 not supported), and requires the latest iTunes installed, and an iPhone 3GS with the 3.0 firmware.
Hotz mentions in a blog post that the jailbreak for Mac is “coming soon.” The iPhone Dev Team did release a unlock for 3.0 which did not work on the iPhone 3GS, but Hotz’s version does (although it doesn’t free you from your current carrier).
