George Hotz is at it again…this time he’s brought the purplera1n down on the iPhone hacking community with his super simple jailbreak tool that is now out for Mac and PC users running the 3.0 firmware.
Running this app with a connected iPhone (3G, 3GS, 2G) will jailbreak it and after a reboot, drop an app called ‘Freeze’ on your iPhone. Run this app, wait for it to finish and then reboot again and you’ll have Cydia installed. Run Cydia and then follow the instructions at iClarified.com to install Ultrasn0w on your iPhone and then reboot again. You should now have an unlocked, and jailbroken iPhone 3GS.
Modmyi.com has a Mac tutorial already up for the new Purplera1n.
As with all these types of things, use caution and expect things to go sideways. Worse case is you do a restore via iTunes in most cases….but proceed with caution and at your own risk.
