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.
MuscleNerd, a member of the DevTeam, posted an interesting tweet. He claims that a new version of PwnageTool to jailbreak the Firmware 3.1.3 will be released soon.
However he also warns the owners of an iPhone 3G or 3GS, suggesting not rush for firmware update. In other words, the improvements of firmware 3.1.3 are minimal, so if you are comfortable with firmware 3.1.2 just stay with that.
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 Cydiaapplications and personalized boot logos.
At this time BlackRa1n is still recommended for Windows users with firmware 3.1.2 and RedSn0w for earlier firmwares.
DevTeam just released PwnageTool 3.1.4. It allows users to jailbreak firmware 3.1.2 on iPhone 2G/3G/3GS and iPod Touch 1G/2G. It also supports OTB iPhone 3GS with firmware 3.1.x. We remind you that if you need unlock, do not update on regular 3.1.x firmware, use Pwnagetool to create custom firmware to preserve old baseband.
Here is a quick howto:
Factory Unlocked iPhone 3G and iPhone 3GS: You do not need unlock, just use PwnageTool to create an ipsw and then use this to update and jailbreak your phone.
iPhone 3G and iPhone 3GS: if you need unlock, use PwnageTool to create a custom firmware with an old baseband. Then update using created custom firmware and install ultrasw0w via Cydia to unlock.
iPhone 2G: Use PwnageTool to do the magic and then restore with iTunes using your newly created .ipsw.The baseband will be unlocked, the phone jailbroken.
iPod Touch 1G: Use PwnageTool to create a firmware image and restore with that .ipsw using iTunes.
iPod Touch 2G: You must already be jailbroken in order to use PwnageTool. If so, create a firmware image and restore with that .ipsw using iTunes.
