Jailbreak iPhone 3G 3GS 3.1.2 with blackra1n for Mac OS X

The 30 seconds all-in-one device jailbreaking tool by @geohot has now been released for Mac OS X. Last week, blackra1n for Windows was released which was the first tool for jailbreaking iPhone (2G, 3G and 3GS) and iPod touch (1G, 2G and 3G) running on the latest iPhone firmware 3.1.2.

UPDATE: An updated version of this guide for blackra1n RC3 with blacksn0w can be found here.

So, what is blackra1n? blackra1n is a 30 second ALL device 3.1.2 jailbreak. Even the ipt3, but the ipt3 is tethered. In order to boot it, just rerun blackra1n.

Jailbreaking instructions for blackra1n on OS X are exactly similar to the one on Windows. Simply download blackra1n for Mac OS X (download link given below) and then follow the step-by-step guide posted here. I will highly recommend using PwnageTool 3.1.4 from Dev-Team if you want to preserve your unlock on iPhone. blackra1n is only recommended for those who are on the official supported carriers like AT&T and do not care about unlocking, or the one’s with iPod touches.
