Fuzzyband is an application that can downgrade the baseband for iPhone 3G. Recently it has been updated to include the support for firmware 3.1.3 baseband 05.12.01. It works only with bootloader 05.08 (early iPhone 3G).
Why do users need to downgrade the baseband? The answer is simple: if they accidentally upgraded the new firmware and need to run unlock software (blacksn0w and ultrasn0w). Unlocked iPhones do not need Fuzzyband. iPhone 3GS users cannot downgrade baseband with Fuzzyband.
Fuzzyband is available for jailbreaked iPhones in Cydia (repository BigBoss, category "System" ).
Sherif Hashim has discovered an exploit which may allow unlock of the latest iPhone OS 3.1.3 baseband 05.12.01. Such unlock utilities for previous baseband versions were called blacksn0w, ultrasn0w и and yellowsn0w. MuscleNerd, the member of DevTeam, has already confirmed it is working. So the timing of the unlcok release is totally up to them right now.
Here is an official update from DevTeam:
"We’ve started to look at his crash but it’s a long road between any given crash and a fully working unlock, and we couldn’t put an ETA on it even if we wanted to. It’s not even guaranteed that an working unlock will come from this particular crash — it’s just too early to tell."
According to the statistics just 14% of iPhone users have updated the firmware to version 3.1.3.
In particular 72.3% are still using firmware 3.1.2, less than 1% - firmware 3.1.1 and 4.6% have previous versions yet. The reasons for this are probably from the fact that 3.1.3 is only a minor update. Another reason could be the uncertainty of the jailbreak.
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:
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.
iPhone hacker Geohot, who created popular utilities blackra1n (jailbreak) and blacksn0w (unlock), posted a message on twitter about the new firmware 3.1.3 released by Apple:
Hopefully some vulnerability in the new firmware will be found.
Enagdget reports that new facts about the 4th generation iPhone were discovered in iPad’s 3.2 SDK:
Buried way inside the platform simulator lies a set of folders dedicated to specific models of iPhone OS-ready devices, including the iPhone 3GS, second generation iPod touch, something called the "K48" (yep, the codename we were told was the internal name for the iPad), and... the "N89."
This "N89." is rumored to be the codename of the next iPhone. Previous versions of the iPhone were named the M68, N82 and N88.
They also have found a bit more than that:
Apple's just released firmware (3.1.3) also includes another new model, the "N80," which we're told will most likely be the next version of the iPod touch.
Rumors say that 4th generation iPod Touch is likely to ship this September, while the next iPhone is expected this June-July.
Along with a new firmware for iPhone and iPod Touch Apple released a new version of SDK - 3.1.3. It's a required update, otherwise Xcode will not recognize or work with your 3.1.3 device. You can download it at iPhone dev center.
As usual the iPhone SDK includes Xcode, the iPhone simulator, and other tools for developing applications for iPhone and iPod Touch. If you want to develop for the iPad, you'll need the SDK version 3.2 instead.
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.
TheBoyGenius report that they have found some very interesting data while analyzing the access statistics to their web site:
We can see that this data is related to the new iPhone firmware 3.1.3 and 4.0!
The iPhone OS 3.1.3 should only be a minor update over the current version and could be released even in several days. Firmware 4.0 will probably be released after testing phase and several private beta versions for developers. Rumors say this new version 4.0 will be released together with iPhone 4 some time in June or July next year.
The DevTeam has just released Pwnage Tool 3.1-3, the new version of the tool for Mac OS that lets you run the jailbreak on iPhones and iPod Touch with firmware 3.1. The new version adds limited support for iPhone 3GS and iPod Touch 2G. It still works with iPhone 2G (EDGE), iPhone 3G and iPod Touch 1G.
The iPhone 3GS is now supported in PwnageTool 3.1.3,assuming the phone was pwned at 3.0 or 3.0.1 - PwnageTool does not support the 3GS out of the box. If your iPhone 3GS has 3.1 preinstalled and is not Pwned then there is no tested jailbreak solution at the moment.
The iPod 2G is now supported in PwnageTool 3.1.3, assuming the iPod 2G was pwned at 3.0 or 3.0.1 - PwnageTool does not support the iPod 2G with 3.1 software out of the box.
