The iPhone Dev Team has found another exploit to unlock iPhone OS 3.1.3 baseband – MuscleNerd of the iPhone Dev Team has tweeted that just re-discovered a crashing command that yellowsn0w, the iPhone unlocking software was originally going to use.

What does that mean? It means he has found another working exploit for the baseband bundled in iPhone OS 3.1.3, which should help them figure out a way to jailbreak and unlock the latest iPhone OS.

The iPhone hacking community has already discovered two working exploits for the baseband 05.12.01 that is bundled in iPhone OS 3.1.3.

MuscleNerd announced on his Twitter page:

Ha just re-found crashing command yellowsn0w was originally going to use before +stkprof. Apple fixed it *accidentally* in 02.28.00.
some commands have come and gone. some command holes have come and gone. this command has come and gone but not the hole:)
it still seems accidental though :) there are no overt signs that they’ve closed the hole, but the byte alignment kills it

Apple has built in this bizzare intepreter into their baseband.

Why is it in production units? Fun!

It is still not clear whether hey’re talking about the same exploit or a different one.

In any case, the iPhone Dev Team and Geohot have at least one working exploit for the 05.12.01 baseband, unlocking iPhone OS 3.1.3 could soon become a reality rather than a dream!

Stay tuned!

The legendary iPhone Dev Team have updated their nice PwnageTool application to version 3.1.5 to support Apple’s recently released iPhone OS 3.1.3 – PwnageTool 3.1.5 for Mac OS X will let you do so safely, preserving your jailbreak and ultrasn0w unlock. (If you use the blacksn0w unlock (at baseband 05.11.07), you need to stay at 3.1.2.)

iPhone 3G and 3GS unlockers should always be very wary to update their firmware. This is no exception. If you make a mistake along the way you may find yourself updating to official 3.1.3 in which case you will lose your unlock, possibly forever.

iPhone 3GS users (regardless of unlock) should stay away from this and all 3.1.3 jailbreak tools unless you know you have your “SHSH hashes” backed up via Cydia. That’s because if you make a mistake you may find yourself stuck at official 3.1.3 with no way to jailbreak or come back down to 3.1.2 to jailbreak.

If you really truly feel that you need to update, this version creates a custom 3.1.3 IPSW for you to restore to on your iPhone 2G, iPhone 3G, iPhone 3GS with early bootrom, iPod touch 1G, and iPod touch 2G with early bootrom. If you don’t know if you have an early bootrom or not, please avoid updating until you learn more.

You don’t need to be pre-jailbroken on anything but the iPod touch 2G early bootrom. And really for that device, it’s faster and easier to use redsn0w 0.9.4 as mentioned in our last post. For that matter, if you have an ipt1g, iphone2g, or iphone3g(and don’t need an unlock), you should use redsn0w too (but version 0.9.3). It’s faster and you won’t have to go through a full restore process (just do an update then run redsn0w, pointing it at 3.1.2 FW instead of 3.1.3).

If you have an iPhone 3GS, PwnageTool works if you’re currently at version 3.1.2 or below (down to 3.0). You don’t need to be already jailbroken — PwnageTool will ask you if you’re jailbroken after you’ve created the IPSW. Don’t use PwnageTool on the iPhone 3GS if you’re at 3.1.3, it just won’t work. Downgrade to 3.1.2 using the methods described here. If you can’t downgrade because you don’t have your 3GS 3.1.2 hashes on file with Cydia, you’ll need to sit out the 3.1.3 jailbreak.

Wow, a day after the iPhone Dev Team released their updated Redsn0w software, Apple releases an update to iPhone OS. This isn’t a significant update to the iPhone OS. It doesn’t introduce new and exciting features to the current hardware but it does fix a number of issues and bugs.

This update fixes and improves the following:

• 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

This update is for all current hardware, iPhone 1G (EDGE), iPhone 3G, iPhone 3GS and all iPod Touch devices. You can easily get the update via iTunes by connecting your device and clicking “Check for Update”

*Note* It’s been confirmed by the iPhone Dev Team that Redsn0w 0.9.2 works with this new iPhone OS update only with iPhone 1G (EDGE) and iPhone 3G and *ONLY* if you don’t care about unlocking. Just point Redsn0w 0.9.2 to the iPhone OS 3.1.2 firmware IPSW — The iPhone Dev Team urges iPhone 3GS and iPod Touch users who wish to jailbreak to stay away from this update until further notice!

The good ol’ folks from the iPhone Dev Team have updated redsn0w after a long time without any updates.

A cross-platform jailbreaking, unlocking, and customizing tool for iPhones and iPod touches. Customizations include boot logos, recovery logos, and “verbose” boot. It’s a standalone program that doesn’t use iTunes (no custom IPSWs are involved).

iPhone Dev Team’s Redsn0w finally supports iPhone OS 3.1.2 but it’s still tether-only for late models such as the iPod Touch 2G if the serial number starts with “MC”, any iPod Touch 3G and iPhone 3GS.

The new version of Redsn0w also adds new features such as, Verbose boot, addition of custom Boot Logos, and bypassing jailbreak if your device is already jailbroken.

Haven’t seen much from the iPhone Dev Team lately but they released an update to their ultrasn0w product that fixes an issue for those running firmware 3.1.x with the 04.26 baseband. Apparently, that specific combination resulted in a missing carrier name in the upper left hand corner of your home screen (Springboard).

Ultrasn0w update from 0.91 to 0.92 fixes that problem, which was important for roaming on your iPhone. You should see that update live now if you have http://repo666.ultrasn0w.com as a Cydia source. If not and you want/need this update then you should definitely add it by going to Cydia -> Manage -> Sources -> Edit -> Add and input the above URL.

GeoHot beat the iPhone Dev Team on this one, but no worries – It’s all good. You can create your own custom pre-jailbroken IPSW and restore it on your iPhone, iPhone 3G, iPhone 3GS, iPod Touch 1G, iPod Touch 2G but sadly, no iPod Touch 3G support, you’ll have to use GeoHot’s Blackra1n to jailbreak.

SUMMARY:

• The iPhone 3GS is now supported out of the box in PwnageTool 3.1.4 (or if you have upgraded to 3.1.x in iTunes)
• The iPod 2G is still supported in PwnageTool 3.1.4 but you must already be jailbroken (we’ll update this if there’s a big demand from non-jailbroken ipt2G owners)
• The iPod touch 3G is NOT supported

DETAILS:

• GOLDEN RULE: If you are using a iPhone 3G or iPhone 3G(S) with ultrasn0w and rely on ultrasn0w to obtain cellular service then you should only update your device with an .ipsw that is made with the new PwnageTool. There are no second chances with this. You need to remember that PwnageTool will provide an upgrade path to newer versions of the iPhone software in the future.
• Please read all parts of this post before downloading and using these tools.
• Read items 1, 2 and 3 again and again.
• PwnageTool will work for the iPhone 3GS
• PwnageTool will work for the iPod touch 2G
• PwnageTool WILL work for Original iPhone (1st Generation), the iPhone 3G and iPhone 3G(S) and the iPod touch (1st Generation and 2nd Generation) but NOT the iPod touch 3rd generation.
• For 3G and 3G(S) users who are Pwned, PwnageTool is your key to updating in the future, just remember to never install an update directly from Apple, always use an .ipsw that has been created with PwnageTool.
• There is no Windows version of PwnageTool it is a Mac OS X tool only, we are not developing a Windows version of PwnageTool.

Apple released iPhone OS 3.0.1 to fix a serious SMS vulnerability in the iPhone OS where your iPhone can be completely taken over by receiving a maliciously crafted SMS message.

In this tutorial, I will show you how to jailbreak iPhone OS 3.0.1 in the same way you would jailbreak iPhone OS 3.0 with redsn0w.

Please follow these instructions clearly and you’ll be a-o-k. Now, before we begin you may notice that we use the iPhone OS 3.0 IPSW to jailbreak our iPhone OS 3.0.1 device, this is no mistake. When you get asked to select the iPhone firmware you have installed then choose the iPhone OS 3.0 IPSW. Please make sure you have updated your device to 3.0.1 by either updating officially via iTunes or restoring via iTunes. Keep in mind that restoring your iPhone will erase your iPhone’s content. Also, please don’t mind the screenshots saying redsn0w version 0.72 – Use the latest redsn0w version, it’ll be the same as the screenshots below.

Note: We are not responsible if your device blows up in the middle of the jailbreak process (it wont) or if your device doesn’t turn on after using this. Use, strictly, at your own risk!

1. First is first, download redsn0w here (for Windows) or here (for Mac OS X)
2. Second, Download iPhone OS 3.0 or whatever firmware you’ll be using to jailbreak – here

The iPhone Dev Team released an update to ultrasn0w (Version 0.9) and the update fixed a majority of problems seen by ultrasn0w users but you may still see a few problems here and there…

Problems you may see include:

• Unusual battery depletion is almost always caused by people choosing to “Restore from backup” instead of “Setup as new iPhone” when iTunes asks you. This isn’t caused by either the jailbreak or the unlock, but it’s a common 3.0 snafu. The fix is to just re-run the official 3.0 restore and choose “Setup as new” this time. Your music and apps and all that will still be synced, but you’ll get rid of any conflicting wifi, bluetooth, or carrier settings. Then just re-run redsn0w and install ultrasn0w.
• Remember, ultrasn0w works with hacktivated phones too, but don’t outsmart redsn0w into thinking you don’t need hacktivation! If you don’t plan on using an official sim, don’t activate via iTunes with such a sim. Just keep your unofficial sim at all times and let redsn0w and ultrasn0w handle hacktivation
• T-Mobile in the USA doesn’t use the 3G frequencies that the iPhones support, so turn off 3G in Settings->General->Network. (Some T-Mobile territories gracefully hand down to Edge mode, but most do not).
• Certain unofficial plans have limitations on whether you can make calls and use data at the same time. That’s not unlock-related.
• Some people have installed previous versions of ultrasn0w using non-standard techniques. While the ultrasn0w 0.9 update should have removed all previous versions of ultrasn0w, these users may have outsmarted our removal. So make sure you don’t still see /usr/bin/ultrasn0w present if you’re at ultrasn0w 0.9 (which doesn’t have such a binary anymore).
• If you don’t need or plan to update to ultrasn0w 0.9 from a previous version, you can avoid having that red badge over Cydia by removing repo666 as a Cydia source. Don’t worry, you can always add it back later :) If you follow us on twitter you’ll be advised of any new updates anyway.
