So this is a minor update, which fixing only the accuracy of the 3GS battery meter and the stability of some third-party app launches. This update is avaliable via iTunes.
New firmware 3.1.3 also introduces a new version of the baseband, the 05.12.01. So if you need unlock do not update! DevTeam also warns us:
If you care about your jailbreak and unlock, don’t update your device – 3G and 3G(S) owners should pay particular attention to this warning.
PwnageTool and redsn0w are not yet compatible with 3.1.3
Experimenters show that the latest version of redsn0w 0.9.2 is able to jailbreak iPhone 2G, iPhone 3G and iPod touch 1G. Just point it at the 3.1.2 IPSW (download here) after doing update or restore to firmware 3.1.3. Sounds like DevTeam will release an updated version of redsn0w that will handle firmware 3.1.3 officially. They say iPod touch 2G with firmware 3.1.3 is also jailbreakable.
Users report that unlock software, blacksn0w and ultrasn0w, doesn;t work with the new baseband.
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.
When asked about PwnageTool, MuscleNerd said via twitter “they can compile now for wxwidgets for redsn0w 0.9, so pwnagetool port can be based on this”, “and so that means, pwnagetool port for windows and linux. For OSX it’s all on @wizdaz of course ”
PwnageTool lets you build custom ipsw files which can include personalized boot logos as well as automatic installation of applications. There is also project called Sn0wBreeze, a port of PwnageTool to Windows. However a port from DevTeam is of course more preferrable.
The latest version of PwnageTool 3.14 can be downloaded here.
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.
MuscleNerd, a member of the Dev-Team, has announced via twitter the release of the new version of PwnageTool.
The software will be able to create a custom firmware 3.1.2 to jailbreak and unlock iPhone 2G, iPhone 3G, iPhone 3GS, iPod Touch and iPod Touch 2G. As stated everything would be ready soon and the tests performed were positive.
