Today is too lucky for everyone in the iPhone 3G and 3GS community as it’s both blacksn0w and blackra1n day. GeoHot released the blacksn0w, the first ever unlock solution for iPhone 3G and 3GS with latest iPhone OS 3.1.2 with baseband 05.11.07, for free. The bonus news is that blacksn0w enables official tethering. Too lucky! Isn’t? And you can un-tether from AT&T and Apple’s shackle, finally.

Also he released blackra1n, a jailbreak for 3.1.2. It has been updated to RC3 with hacktivation support, 15 second speed improvement, Tiger+PPC support, and installation of the latest blackra1n.app

Is this for everyone? Yes, it’s. Here are the simple steps to jailbreak and unlock iPhone with blackra1n and blacksn0w. More detailed steps will be posted here by today, after I tried these solutions on my iPhone 3GS and my friend’s iPhone 3G.

For loyal blackra1n user:

Jailbreak Steps:
1) Run the blackra1n.app on your iPhone, if you still keep it
2) Icy will be replaced by an option “ra1n”
3) Install “ra1n” to upgrade your app
4) Run blackra1n.app again

Unlock Steps:
5) Install “sn0w”, which will be seen after running blackra1n.app in the step 4

That’s it! Now is the time to enjoy your unlocked iPhone

For New User (Just like me):
These steps are for those who upgraded iPhone OS to latest 3.1.2 with 05.11.07. If you never jailbroke or unlocked it, you better upgrade it to latest OS.

1)  Go to blackra1n.com
2)  Click on the logo corresponding to your operating system and download the files
3)  Run the downloaded file
4)  Click “make it ra1n”
5)  After the iPhone reboots, blackra1n.app will appear
6)  Run blackra1n.app
7)  Install blacksn0w

You also enjoy your unlocked iPhone.

For Pwnage User:
If you jailbroke using pwnage or deleted your blackra1n.app, you will have to wait till later today as blacksn0w will be added to Cydia, and instructions will be posted here and there.

For 2G iPhone User:
Blacksn0w isn’t an option for you. But BootNeuter is, a completely free permanent unlock for your 2G. Of course, blackra1n will work great, and even hacktivate for you.

GeoHot thanked ih8sn0w for bringing the at+xemn command to his attention. This is the injection vector used to get code running on the baseband. You can soon expect him to write a technical post about how it works.

As a final note, GeoHot wrote in his blog “This may be the best iPhone users ever have it. Be sure, if you have a 3GS or iPod Touch 3, to use Cydia’s “On File” or Firmware Umbrella in order to be able to restore to 3.1.2 in the future. And as always, the baseband cannot be downgraded, so be *super* careful with updates if you need the unlock.”

Enjoy Jailbreaking and Unlocking!
