Geohot Releases blackra1n to Jailbreak Any iPhone Running iPhone OS 3.1.2 for Mac

Jailbreak iPhone 3GS using purplera1n

If Mac users had felt left out when Geohot released blackra1n for only Windows users then I have some good news. 

He has released his amazingly simple tool to jailbreak any iPhone running iPhone OS 3.1.2 for Mac users as well.

The details for the Mac version of blackra1n remain the same. I’m providing it again for the benefit of Windows users:

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

This is based on the assumption that you don't have one of those new iPhone 3GS models with an updated boot ROM.

He has issued the following warning for iPhone 3G and iPhone 3GS users who want to unlock their iPhone:

Warning 3g and 3gs unlockers, do not upgrade to 3.1.2 using iTunes if you want to keep your unlock. Baseband cannot be downgraded. Check out the dev team's offerings. Also blackra1n doesn't hacktivate.

So if you want to unlock your iPhone then you should use iPhone Dev Team’s PwnageTool 3.1.4, which allows you to jailbreak iPhone OS 3.1.2 and also preserve the baseband so you can use UltraSn0w to unlock it.

If you want to only jailbreak your iPhone and don’t care about unlocking it, then you can try blackra1n by downloading it from this link (click on the Apple logo).

After jailbreaking your iPhone, it installs the blackra1n iPhone app, which can be used to install the unofficial App Stores such as Cydia (recommended to only install this one), Icy and Rock.

Please remember hacking your iPhone could void its warranty. So please proceed with caution and at your own risk. It is always a good idea to take a backup of your iPhone before you hack it, refer to this post for more details.

If the solutions works for you, don’t forget to drop over at the blackra1n’s website to give Geohot a donation for all his hard work.

As always, if you give it a shot let us know how it goes.
