George Hotz, the 19-year old whiz kid who made headlines two years ago for being the first to successfully unlock Apple’s original iPhone all by himself, is again drawing the spotlight for creating and releasing the first-ever jailbreaking tool for the new iPhone 3GS.

Dubbed “purplera1n,” the software is currently in beta and available for Windows-only, but Hotz said a Mac version is next on his list. Those interested in using the tool should first backup their iPhone 3GS running iPhone Software 3.0 and make sure they have iTunes 8.2 installed.

Hotz boasts that the binary size of purplera1n is smaller than a C++ hello world application — essentially the most basic piece of software that can be written for modern day computer systems, which simply spits out the phrase “hello world” and terminates.

“No 20MB thing that needs to be torrented,” he wrote in a blog post. “And no IPSW to download. This is how jailbreak should be!” We agree.

After downloading purplera1n, jailbreaking takes just a few simple steps. “Connect your iPhone normally. Click ‘make it ra1n’. Wait. On bootup, run Freeze, the purplera1n installer app. Hopefully you’ll figure out what to do from there,” Hotz wrote.

The Glen Rock, New Jersey native said he doesn’t normally make tools for release to the general public, and prefers to wait for the unofficial iPhone dev team to tackle such matters, but has grown annoyed that they’re apparently waiting for version 3.1 before releasing a jailbreak.
