iPod4G At iOS 4.3.1 *Untethered Jailbroken*


i0n1c () has released a YouTube Video showing off the iPod Touch 4G jailbroken in an untethered state on iOS 4.3.1. There is no ETA on the release but hopefully it will be out soon.  Here is his official statement:

Meanwhile everyone should have noticed that my prediction became true and Apple released iOS 4.3.1 in order to fix the PWN2OWN vulnerability in Safari. It was very unlikely that Apple also fixed the kernel vulnerability I used for my untether exploit. Mainly because the kernelcache binary is about 8-10 MB in size and the likelihood that Apple finds the same vulnerability in that short amount of time was very low. However you never know until you try it. So this morning when I woke up and saw that Sn0wbreeze 2.4 beta was released I thought it would be fun to create a new video. Unfortunately Sn0wbreeze does not work with my iPad 1 and so I had to test with my iPod 4G. In the video you can see how I switch off the iPod, then restart it, show the version, show that it is tethered and has the multitasking gestures, i show that you can buy ringtones and then I show cydia and the ninja jump game from last time. Because several people misunderstood me in the past: a. I repeatedly stated that I will not release a jailbreak tool – I will only give out the untether. I did not try yet, but if it is feasible the untether could be a cydia package. b. While the vulnerability I use is in the iPad 2 kernel my untether will NOT SUPPORT the iPad 2, because there is no way to install it there (bootrom exploits fixed). – however Comex is working on that part. c. I am not giving out any ETA again, because the Jailbreak community is simply nuts. Last time I gave an ETA and even before that had passed I got constantly insulted by people that were demanding an immediate release. Sorry guys the more you insult people with the knowledge to actually do what YOU WANT the less motivation there is to use our free time to give it to you. d. The only reason why I did not finish the untether before the ETA was due to unexpected work overload in my real job. It had nothing todo with the untether being too hard or unreal. e. I don’t know why the dev team has not released a redsn0w that does tethered jailbreak for 4.3.1 – I would prefer that to be available, cause sn0wbreeze obviously does not work 100% yet. f. If you want to learn more about iPhone kernel hacking/exploitation you should come to SyScan Singapore at the end of April. http://syscan.org/index.php/sg/program

Check iPhone 3GS Bootrom In Windows And Mac

So you want to check your iPhone 3GS bootrom?  There are a few easy ways to do it without hooking it up to the computer, but the best way is to hook it up to the computer.

Windows:

1. Plug your iPhone into your computer. (iTunes should be open)

2. Turn the iPhone 3GS power off.

3. When the phone is turned off and plugged into your computer, hold down the power button and the home button for 10 seconds.  After 10 seconds release only the power button and continue to hold the home button.

4. Your iPhone 3GS screen should look like it is turned off and you will get a message from iTunes saying that the iPhone is in recovery mode.  Just ignore it.  If you see a restore logo on your phone you did not do it correctly and should start over.  If your phone’s screen looks like it is turned off, you did it right!

5. Go to start ->Control Panel -> Device Manager.  Then Expand Universal Serial Bus Controllers.

6. You will see Apple Mobile Device USB Driver.  Right click on it and hit properties.

7. Go to the Details tab and then select Device Instance Path.  At the end you will see iBOOT-359.X.  If you have 359.3, you have the old bootrom.  Anything else will be the new bootrom.

8. To get out of DFU mode just hold down both the power and the home button until you see the Apple logo.
