Guide: purplera1n, iPhone 3GS Jailbreak Solution

George Hotz (aka Geohot), a member of the iPhone Dev Team and the first to unlock the original iPhone (iPhone 2G) is back. He has released a software called purplera1n to jailbreak iPhone 3GS.

He seems to have released it on his personal blog against the wishes of others in the Dev Team as he didn’t seem to agree with the decision that the jailbreak for iPhone 3GS had to wait until iPhone OS 3.1.

This one is only for iPhone 3GS users, if you are an iPhone 3G users, please checkout our step-by-step guide to jailbreak iPhone 3G running iPhone OS 3.0 for Windows or Mac users.

Geohot has explained the reason for releasing purplera1n on his personal blog:

Normally I don’t make tools for the general public, and rather wait for the dev team to do it. But guys, whats up with waiting until 3.1? That isn’t how the game is played. We release, Apple fixes, we find new holes. 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.

He has also provided the instructions to use it:

Download it. Make sure you have windows(but not 7), the latest iTunes installed, and an iPhone 3GS with 3.0 firmware . 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.

You can download purplera1n from this page.

In the meantime, Dev Team have also published a video demonstration of their unlocking solution UltraSn0w for iPhone 3GS.

They have provided the following details about their unlocking solution for iPhone 3GS:

Our ultrasn0w program uses the at+xlog crash as an injection vector of our unlocking payload — and it does so on the 3GS in exactly the same way as on the 3G!  But this injection vector will be lost if you update to 3.1 using the official Apple IPSW, which updates the baseband.  So stay away from official 3.1 IPSWs until we release the tools that let you update the firmware without updating the baseband.

Before you use purplera1n to jailbreak iPhone 3GS, please remember that hacking your iPhone could void its warranty and at your own risk so please proceed with caution.
