The other day we heard that Apple has released iOS 6.1.3 Beta 2 to developers, the update is designed to fix the passcode bug found in iOS 6, and now it would appear that the update may actually break the evasi0n iOS 6 jailbreak.
The iOS 6.1.3 Beta 2 which was recently released to developers apparently patches one of the five exploits that were used in the iOS 6 Jailbreak, the exploit was a time zone bug.
iOS 6 Jailbreak
Apparently the evasi0n iOS 6 jailbreak needs all five exploits for the jailbreak to work, so it looks like the iOS 6.1.3 software update to break the evasi0n jailbreak, unless the team behind the software can find another option before iOS 6.1.3 is released.
There are no details as yet on exactly when Apple will release the final version of iOS 6.1.3, although considering that it fixes the passcode exploit that could give anyone access to your iPhone we suspect it will be sooner than later.
