Geohot has released his BlackSn0w utility. BlackSn0w is an unlock for the iPhone 3G and iPhone 3GS. It supports the latest firmware 3.1 and 3.1.2 with baseband 05.11.07 and enables official tethering. Available for both Windows and Mac.
Here is a quick tutorial:
If you havn't done the jailbreak: go to blackra1n.com, download blackra1n, run it, follow the instructions (it is really simple) to perform the jailbreak. Run balckra1n app on iPhone and install BlackSnow.
If your device is already jailbroken - run Cydia, add repository blackra1n.com and install blacksn0w. That's it!
The latest version of blackra1n is RC3. It now has hacktivation support, 15 second speed improvement, Tiger+PPC support.
PS: If you just bought a new iPhone 3GS or have one that was made recently (approximately after 40th week after iPhone 3GS release): your device has a new BootROM. Unfortunately it is impossible to run regular jailbreak with this new BootROM. There is a sloution - tethered jailbreak. Everything including unlock will work fine. However every time you restart your iPhone, you need to plug it to a computer with blackra1n installed.
Geohot has posted the first screenshot of his blacksn0w baseband 05.11.07 unlock for the iPhone 3G and 3GS. The unlock which will be run after completing a jailbreak with the blackra1n jailbreak is expected to be released on November 4th.
GeoHot has just released a new video which shows his new hack in action. It's called Blacksn0w and is able to unlock the new baseband 05.11.07 of the iPhone 3G and iPhone 3GS.
This new baseband appeared in firmware 3.1. So all users who own locked iPhone can unlock it and use with any cellular provider. Users who have upgraded to firmware 3.1 or 3.1.2 by mistake can also use blacksn0w.
The famous iPhone hacker GeoHot started working on unlock of the new baseband 05.11.07 several days ago. Today he published the first results that can be defined as very positive.
So he managed to take control of the baseband, running the code written directly by himself. This measns that soon all users of locked OTB iPhones with firmware 3.1 and 3.1.2 will be able to unlock ther devices.
Few hours ago GeoHot left a new message on Twitter - he officially started looking for an exploit in the new baseband 05.11.07.
All iPhone 3G/3GS owners with native firmware 3.1 or higher will be finally able to unlock the phone. This also applies to iPhone owners who updated to firmware 3.1 or 3.1.2 by mistake.
