We have good news for anyone who accidentally updated to iPhone OS 3.1.3, which in turn updated the baseband on the device. GeoHot, iPhone Hacking expert and creator of popular unlocking and jailbreaking tools, such as Blackra1n and Blacksn0w, has discovered a working exploit for baseband 05.12.01.

Geohot has tweeted the hash tag of the baseband crash “for safekeeping”:

d8b50dc95d7906e3ff6155331a534b55d0f6cac1=good.

In addition, iHackintosh has also published the conversation between Visnet (iHackintosh reader), Geohot and MuscleNerd:

<visnet_> What does geohot tweet mean?
<geohot> its my bb exploit for safekeeping
<Par4doX> geohot: did you turn that over to the dev team or are you doing something with it?
<geohot> my days of turning things over are done
<geohot> i hope its different from the one they have
<geohot> but they prob already have it
<geohot> its the one i orig wanted to release blacksn0w with
<Par4doX> it’s still there in the new bb
<geohot> yep, just checked
<geohot> but then opted to use xemn since it was public
<Evan> Oo, it carries over from 05.11 to 05.12?
<geohot> why wouldn’t it, apple doesn’t fix things proactivly
<MuscleNerd> geohot we prob should figure out a way to know if we have same exploit double blind, otherwise we may release 2 different ones at same time
<geohot> any suggestions?
<MuscleNerd> not sure how to do that without making it easy to brute force though
<geohot> yea, i salted the hash
<MuscleNerd> yeah
<MuscleNerd> hmm maybe if we both hash the stack dump
<Confucious> Can you two take this out of public sight?
<MuscleNerd> the stack itself, not the header before it or the registers after it
<Her> muscle: any notice about the exploits are the same ?
<geohot> we are working on it
<geohot> cryptography, perfect for people who don’t trust each other

The conversation indicates that both the iPhone Dev Team and Geohot have a working exploit for the latest baseband and could release tools to jailbreak and unlock iPhone OS 3.1.3.

Stay tuned!

GeoHot has released a free unlock for the iPhone 3G and iPhone 3GS called blacksn0w. You can install blacksn0w from the blackra1n application installed on your iPhone when jailbreaking with blackra1n. You can also install blacksn0w from Cydia by adding blackra1n.com to the Cydia source list.

blacksn0w is a free unlock for the latest iPhone 3G and 3GS

blacksn0w is also available on Cydia, add blackra1n.com as repo
requires firmware >= 3.1 and baseband 05.11.07

If you happen to use blacksn0w and run into Wi-Fi issues, GeoHot suggests you try to Reset Network Settings in Settings -> General -> Reset -> Reset Network Settings.

GeoHot has released his latest tool to jailbreak iPhone OS 3.1.2 on the Mac platform, so for all those Mac users wanting a 30s or less jailbreak can now do so. Along with Blackra1n for Mac OS X, Blackra1n was updated for the Windows platform to fix various bugs on the Windows application.

So, what is blackra1n? blackra1n is a 30 second ALL device 3.1.2 jailbreak. Even the ipt3, but the ipt3 is tethered. In order to boot it, just rerun blackra1n.

Warning 3g and 3gs unlockers, do not upgrade to 3.1.2 using iTunes if you want to keep your unlock. Check out the dev team’s offerings. Also blackra1n doesn’t hacktivate.

Updates to blackra1n:

• Unlock
• Hacktivation
• Keep legit activation if activated before running app
• 15 seconds faster
• Tiger + PPC support

Some days ago we reported about GeoHot’s Blackra1n application. Well, GeoHot finally released blackra1n. I mentioned that I wasn’t sure if it would work strictly on the iPod Touch or if it will work on all devices and now that the program is released I can safely say it’ll work with all devices. Blackra1n also jailbreaks Apple’s latest iPhone OS 3.1.2 – So you can jailbreak iPhone OS 3.1.2 with Blackra1n

Currently, blackra1n is for Windows only. Windows users have always been left out with PwnageTool being Mac only now us Mac users can suffer for a little while.

So, what is blackra1n? blackra1n is a 30 second ALL device 3.1.2 jailbreak. Even the ipt3, but the ipt3 is tethered. In order to boot it, just rerun blackra1n. As far as donations go, they are much appreciated, but not until after blackra1n works for you. I never ask for donations before the tool is released.

Warning 3g and 3gs unlockers, do not upgrade to 3.1.2 using iTunes if you want to keep your unlock. Baseband cannot be downgraded. Check out the dev team’s offerings. Also blackra1n doesn’t hacktivate.

Apparently it’s a 30 second jailbreak for all devices running iPhone OS 3.1.2.

Anyone eagerly awaiting for a jailbreak for the iPod Touch 3G (Third Generation) will be absolutely pleased to know that GeoHot has successfully jailbroken the iTouch 3G and will have an application coming out soon that will do just that – blackra1n – However, I am not completely sure if this is strictly for the iPod Touch or if it’ll work for all devices. Guess we’ll find out when it’s released!

10 seconds. and may work for every version of software *ever*, based on the prettiness of the exploit

The release for his jailbreak tool should be released within the next day or so. Stay tuned!

Can’t wait for the iPhone Dev Team to update their tools for the iPhone 3GS? Well, George Hotz (aka Geohot) has released a very simple application called purplera1n to jailbreak your iPhone 3G S! Both Mac OS X and the Windows application have very similar interfaces so this tutorial will work for both operating systems (Windows is being used in this tutorial). Before we begin, some important notes worth mentioning:

• This one is only for iPhone 3GS users. iPhone and iPhone 3G users use this tutorial
• Make sure you’re running firmware 3.0 (If you’re not sure then you most likely do have iPhone OS 3.0)
• Jailbreak apps like WinterBoard, VOiPOver3G etc don’t seem to be working on iPhone 3GS, so you might have to wait for the developers to release updated version of the jailbreak apps
• Use at your own risk. Please pre-read before attempting anything so you know what you’re getting yourself into ahead of time.

Lets begin:
1. Download purplera1n HERE – for Mac OS X or HERE – for Windows
2. Once you have it downloaded, double click the .exe that you downloaded (if on Windows). If on Mac OS X double click the .zip and it should unzip and then double click the purplera1n.app icon to launch the application.

Geohot has done did it again with a complete software unlock for out-of-the-box iPhone’s running 1.1.2/1.1.3.

Instructions are provided within the RAR archive. The procedure involves downgrading back to system software 1.0.2; however, Geohot notes that other versions may work. See here for [older] downgrade instructions. Put your phone into DFU mode to allow the software restore/downgrade; I use iNdependence for that.

If you encounter problems or have any questions — please search or ask in our forums.

Visit the source link for Geohot’s technical explanation in achieving this once said to be impossible unlock.

Looks like iPhone hacker and hardware guru, Geohot, has done it again by unlocking an OTB 1.1.2 iPhone. It’s not the easiest procedure but you can bet that will follow sooner or later. The process entails downgrading the iPhone’s boot loader via hardware hack. Details and instructions available at the source link. Kudos!

If you don’t know what you’re doing, I recommend waiting for a complete software solution. Stay tuned.

Steve-Jobs.com has released an updated pdf guide of their refined version of Geohot’s hardware unlock. This is by far the easiest to follow, most comprehensive guide on how to unlock your iPhone using Geohot’s method without the messy soldering.

Click here to download our mirrored copy of the guide.

As promised — the steps to achieve a full hardware unlock of the iPhone. Rather than me copy/paste directly from geohot’s blog, just follow the link below. It’s divided into separate blog posts coinciding with his wonderful sense of humour. You’ll laugh, you’ll cry, you’ll potentially end up with an unlocked iPhone.

I must warn you: it’s definitely an advanced procedure not intended for the faint of heart. If you have the skills, or the balls, have at’er. It’s currently the only working method aside from going the Turbo SIM route; however, Bladox remains out of stock. I feel for those less fortunate, really.

My spidey senses are tingling (again)… I can feel a complete software unlocking coming soon.

Kudos George, and everyone else involved.
