As expected, DevTeam has jumped the gun and used Geohot’s everlasting limera1n exploit to release iOS 6 Beta 1 tethered JailBreak. The devices which supports iOS 6 Beta 1 tethered JailBreak are iPhone 3GS, iPhone 4 and iPod touch 4G. This is due to the fact that the exploit is dependent on the hardware which can’t be killed in anyway.
Things that should be kept in mind while JailBreaking your iDevice on iOS 6 Beta 1 are:
1) The JailBreak wouldn’t preserve the BaseBand of your iDevice. So if you rely on a software unlock and preserving the BaseBand of your iPhone since iOS 5 release, you should keep yourself away from this tethered JailBreak.
2) The JailBreak is meant only for the developers for testing purpose. If you are not developer and your UDID is not registered into Apple’s developer account, we advise you not to use the JailBreak. The reason behind the early release of this JailBreak is to make the developers ready their third party applications/tweaks when the JailBreak is made public on final version of iOS 6.
3) No Cydia would be installed onto your iDevices. If you don’t know about afc2 and SSH, there’s no reason why you should use iOS 6 Beta 1 untethered JailBreak. The incompatibility of the Cydia is because it’s not yet updated with the latest SDK kit. The only access you would get to the device is through SSH and afc2.
4) It will not hacktivate you iPhone. Thereby, not letting you surpass the emergency call screen through any method. Hence it’s advised that you shouldn’t pirate Apple’s developer firmware. Only developers should have the access to these builds with registered UDID’s.
5) It’s only a tethered JailBreak which means you would need to boot tethered every time your device reboots if either Cydia or Safari have stopped working. The option to boot tethered is available on Redsn0w itself. So you all you need is an access to a PC/Mac every time the device reboots.
Please consider all these points in mind before moving ahead for the tethered JailBreak. You can download the Redsn0w0.9.13dev1 from the links below:
