Jailbreak iPhone, iPod Touch, iPad

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.

iPhone OS hacker, GeoHot, released Blackra1n RC2 today, an updated jailbreak utility for the iPhone 3GS and iPod Touch.

This version provides a tethering jailbreak for the new iPhone 3GS with the updated Bootrom. GeoHot lists these new features on his blog:

• Fixed 3G issues
• Tethered jailbreak for 3.1 OOTB ipt 8GB and new 3GS units
• Fixed Icy issues
• Both Windows and Mac

Apple has updated the BootROM for the iPhone 3GS to iBoot-359.32. This software upgrade is reportedly not vulnerable to an exploit hackers previously used.

MuscleNerd, a member of the iPhone Dev Team, noted this is the first time ever that Apple has done a BootROM update in the middle of a product line, without a new hardware model. The Dev Team is a group of hackers who release tools used to exploit the iPhone OS. With the new iBoot hackers will not be able to use “24kpwn” exploit.

This means that anyone who will buy an iPhone 3GS these days, will not be able to jailbreak and unlock it, probably for a very long time.

And after the various Key and provocations made by GeoHotz, the DevTeam has decided to write a new article on the official blog with good news for all owners of an iPhone 3GS! The DevTeam has verified that the exploit called 24Kpwn (used for the first time to unlock the iPod Touch 2G) is still valid and it works wonderfully for iPhone 3GS.

It seems the new version of bootrom used by Apple in 3GS dates back in August, a few months before the release of 24Kpwn, so there was no time to solve the problem.

In addition, the new daemon released by the team under the name of ultrasn0w (unlock for iPhone 3G) will work with iPhone 3GS.

New versions of redsn0w (jailbreak) and ultrasn0w (unlock) with iPhone 3GS support will be released soon.
