By now we know that iPhone jailbreaking has become a popular challenge among a dedicated developer crowd and freeing the phone from Apple’s chains is a matter of “when”, not “if”. If you have the new iPhone 3GS, you can open up your phone now, less than month after the new model was announced.
The first jailbreaking tool for the iPhone 3GS was released late yesterday by George Holtz, a young developer who also jailbroke the original iPhone. Called “purplera1n”, only Windows XP and Vista users can unlock their iPhone. A Mac version is promised to follow shortly.
While Holtz recommends that a full backup of the phone should be made before running the software, the jailbreaking procedure is simple:
“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. Best tutorial gets linked to from purplera1n site. This tool is beta.”
Holtz indicated that he got impatient with a 3GS jailbreaking tool being made available to the public: “Normally I don’t make tools for the general public, and rather wait for the dev team to do it. But guys, what’s up with waiting until 3.1? That isn’t how the game is played. We release, Apple fixes, we find new holes.”
And he believes that this “game” will be played for a while: “It isn’t worth waiting because you might have the “last” hole in the iPhone. What last hole … this isn’t golf. I’ll find a new one next week.”
The tool can be downloaded free of charge from purplera1n.com.

The first jailbreaking application for the iPhone 3GS is now available. The tool, called purplera1n, will only allow the installation of unofficial third-party applications, but will not unlock the iPhone 3GS.

Before I get into the details, I must remind you that jailbreaking (a software hack) your iPhone is not an Apple-authorized operation and can result in voiding your device warranty. But if you want to dive into the cookie jar of Apple-unsupported apps, carry on reading.
George Hotz, a long-time Apple hacker, has released for the general public a tool that enables Windows users (not version 7) to jailbreak the iPhone 3GS, and older models running the 3.0 software update. The tool does not perform a carrier unlock, which would allow users to use sim cards from other wireless providers than the one they bought the device from.
