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.”

Apple has just released new firmware 3.1.3 (7E18) for iPhone 3GS, iPhone 3G, iPhone 2G, iPod touch, iPod touch 2G and iPod touch 3G.

The update includes:

• Improves accuracy of reported battery level on iPhone 3GS
• Resolves issue where third-party apps would not launch in some instances
• Fixes bug that may cause an app to crash when using the Japanese Kana keyboard
• Other security updates (more info)

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.

DevTeam released PwnageTool 3.1. This utility will allow users of iPhone 2G, iPhone 3G, iPod Touch to run jailbreaked firmware 3.1. We still recommend staying on firmware 3.0/3.0.1 for as long as possible. The 3.1 firmware is not worth it. But if you really want 3.1. Here are the details:

1. If you are using a 3G iPhone with ultrasn0w and rely on ultrasn0w to obtain cellular service, then you should only upgrade to 3.1 with a PwnageTool created .ipsw. Never update using Apple’s unmodified firmware. Stay away from Apple’s direct updates.
2. This version of PwnageTool WILL NOT work for the iPhone 3GS and iPod Touch 2G/3G.
3. PwnageTool WILL work for Original iPhone (1st Generation), Original iPod touch (1st Generation) and the iPhone 3G.
4. It works only with Mac OS X.
5. Future releases of PwnageTool and RedSn0w will be soon with more functionality.

Here is per device info:

iPhone 3G (unlocked): This model of iPhone 3G doesn’t have an Service Provider lock (aka factory unlocked) and you are able to put any SIM card into the phone and get service. Your phone is already unlocked so you do not need to worry about baseband updates, simply upgrade to 3.1 using iTunes and then use PwnageTool to create an ipsw and then use this to jailbreak your phone.

iPhone 3G (locked): You need to preserve 3.0 baseband. Create a custom firmware.

iPhone 2G (1st Generation): Use PwnageTool to do the magic and then restore with iTunes using your newly created .ipsw, you don’t need to worry about anything, the baseband will be unlocked, the phone jailbroken.

iPod touch 1G (Original iPod Touch): Use PwnageTool to create a firmware image and restore with that .ipsw using iTunes.

iPod touch 2G: Sorry, no support at this time within PwnageTool, use Redsn0w for an earlier (pre 3.1) firmware release instead.

iPod touch 3G (New iPod Touch): Sorry, no support at this time within PwnageTool.

You can download PwnageTool 3.1 in our utilities page.

Good news is that you can still use redsn0w 0.8 to jailbreak firmware 3.0.1. Here’s the step-by-step plan:

1. Download both firmware 3.0 and firmware 3.0.1 (link).
2. Download redsn0w 0.8 (link).
3. Update or restore to official 3.0.1 in iTunes.
4. Run redsn0w.
5. When redsn0w asks you to identify the IPSW used, point it at the 3.0 IPSW instead of the 3.0.1 one.
6. Follow the instructions.
7. After the jailbreak, reinstall ultrasn0w 0.9 if you need the unlock.

Great news for all iPhone 3GS users. DevTeam updated ultrasn0w, software that unlocks iPhone with firmware 3.0. Now it supports iPhone 3GS!
