The iPhone Dev-Team has released PwnageTool 3.1.5 for Mac OS X. It allows iPhone and iPod Touch users to safely upgrade to firmware 3.1.3. With PwnageTool you can preserve jailbreak and ultrasn0w unlock. But if you’re using the blacksn0w unlock with baseband 05.11.07 you will need to stay at firmware 3.1.2.
PwnageTool 3.1.5 creates a custom 3.1.3 IPSW for the following devices:
iPhone 2G
iPhone 3G
iPhone 3GS with early bootrom
iPod touch 1G
iPod touch 2G with early bootrom
Warning! Don't try to use this tool if you have iPhone 3GS with firmware 3.1.3 - it just won't work. If you have iPod Touch 1G, iPhone 2G or factory unlocked iPhone 3G , try to use redsn0w - is would be much easier.
H8sn0w has just released the new version of Sn0wbreeze 1.4. Sn0wbreeze is a jailbreak utility with functionality similar to PwnageTool. The new version supports firmware 3.1.3 jailbreak for the following devices:
iPhone 2G
iPhone 3G
iPhone 3GS - old bootrom
iPod Touch 1G
iPod Touch 2G - non MC
Sn0wbreeze is a Windows application, so Mac users have to wait for the upcoming release of PwnageTool by the DevTeam. Alternatively, both Mac and Windows users can use Redsn0w to run jailbreak (no custom firmware though).
You can download the new version of sn0wbreeze here.
MuscleNerd continues to argue that we should not use sn0wbreeze. Especially users who have unlocked their iPhone with blacksn0w utility:
iH8Sn0w has released a beta of Sn0wbreeze a software utility which jailbreaks the iPod Touch 1G, 2G and iPhone 2G, 3G, and 3GS (old bootrom & non MC). The software runs on Windows XP, Vista, 7 (32 or 64 bit). Sn0wbreeze is similar to PwnageTool for Mac. It will allow you to create custom ipsws which can be built to include Cydia applications and personalized boot logos.
At this time BlackRa1n is still recommended for Windows users with firmware 3.1.2 and RedSn0w for earlier firmwares.
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.
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.
