iOS 4.1 Jailbreak Using New Bootrom Based Exploit Confirmed !

The iPhone hacker (pod2g of Chronic Dev Team) who previously found the 24kpwn exploit has successfully managed to find another bootrom based exploit which can jailbreak all iOS based devices on the latest iOS 4.1 firmware. What this means is that the next jailbreak most probably is going to be based on bootrom exploit which unlike JailbreakMe will enable users to change boot and recovery mode logos among many other things.

Members of both iPhone Dev Team and Chronic Dev Team confirmed this on Twitter:

cpich3g: congrats to @pod2g for the latest exploit and also @p0sixninja who have been trying for months.

pod2g: iPhone 4G iBSS 4.0.1: iv=91f94e5d726a2d2f2c7ffad58d4f3b77 key=d05c3c40db40e738926f811b8b1314038d26096c4102461698a49098c47a3fe6

MuscleNerd: Crazy timing that @pod2g got latest exploit just as 4.1 went public (lots of work left…keep away from 4.1 for now!)

Also, the best thing about a low-level bootrom exploit is that Apple wont be able to patch it simply by releasing a new firmware update. Instead, it will require Apple to release a revised hardware version of iPhone 4, iPhone 3GS, iPad and the iPod touches with new bootroms in order to patch the bootrom exploit. This is the reason why iOS devices (like iPhone 3GS (new bootrom), iPhone 4, iPad, iPod touch 3G / 4G) which shipped after November 2009 are currently not jailbreakable via PwnageTool because it uses the 24kpwn bootrom exploit, already patched by Apple.

Stay tuned as we will keep you updated as soon as we get more info about this!

UPDATE 1: pod2g has just tested the exploit on iOS 4.1 (final version) and confirmed that it is working!

Works on 4.1 (!) iBSS iv=c2c5416472e5a0d6f0a25a123d5a2b1c key=1fbc7dcafaec21a150a51eb0eb99367550e24a077b128831b28c065e61f894a0

UPDATE 2: Another confirmation, the new bootrom exploit will work on the newly released 4th-gen iPod touch, iPhone 4 and even iPad !

That latest exploit from @pod2g confirmed to work beyond iPhone4…also on at least iPad and yesterday’s iPod4G too :)
