A few days back I released a  guide for jailbreaking iPhone 3G/3GS and iPod Touch 2G/3G 3.1.2 firmware with Blackra1n. But it worked only in Windows and not in Mac OS X. But now the Mac OS X version of Blackra1n has been released and here is a guide to jailbreak iPhone 3G/3GS and iPod Touch 2G/3G in Mac OS X.

NOTE: Those who don’t care about changing your SIM should only do this. If you want to do that then you should jailbreak your iPhone with PwnageTool 3.1.4.

Just download Blackra1n for Mac OS X and follow this guide to jailbreak your iPhone 3G/3GS and iPod Touch 2G/3G in Mac OS X.
