Yes its true! Although the kernel based exploit that has been used in GreenPois0n, PwnageTool 4.2 and Sn0wbreeze 2.2 for iOS 4.2.1 untethered jailbreak has been patched in the betas (beta1, beta2, beta3) of iOS 4.3, but it won't be much of an issue as a security researcher named Stefan Esser has already got an exploit for iOS 4.3 untethered jailbreak. It has been confirmed by the Stefan himself and by MuscleNerd, who happens to be one of the core members of iPhone Dev-Team.
Tweet by Stefan Esser (@i0n1c):
I hope iOS 4.3 comes out soon. I want to get the untether out as fast as possible :P
Words by MuscleNerd:
And even though 4.3 is just around the corner, the exploit used has already been closed in the latest 4.3 betas, so it made sense for the 4.2.1 untether to be released when it was. It also appears that a security researcher named @i0n1c has a 4.3 untether ready for when Apple releases the final 4.3 FW, so it may not be a long wait at all with 4.3!
According to Stefan, he is just waiting for the release of iOS 4.3 final which is expected on February 28th, 2011. If he releases the exploit now, it will be of no use as Apple might patch his exploit with another beta of iOS 4.3. So, after the release iOS 4.3 final, we should expect two things from iPhone Dev-Team:
- iOS 4.3 jailbreak tool which will be based on Stefan's exploit
- The next version of Ultrasn0w tool which will unlock iPhone 4 4 02.10.04, 03.10.01 & 04.10.01 baseband.
For those who don't know, yesterday iPhone Dev-Team released official version of PwnageTool (v4.2) for untethered iOS 4.2.1 jailbreak on almost all iDevices except iPhone 2G. Soon after PwnageTool 4.2, iH8sn0w released his much awaited Sn0wbreeze (v2.2) tool which can jailbreak iOS 4.2.1 on iPhone 4/3GS/3G, iPod Touch 4G/3G and iPad (Wifi+3G).
