Finally Apple has released the update to iOS 6.1.2 which promises to solve the problems that have been found in iOS 6.1, which caused users to use Exchange accounts You will notice excessive consumption of both mobile data and battery.
This update is Build 10B146 and apparently it is compatible with all devices, although there are reports that both the iPad mini and the fourth generation iPad would be receiving it as Build 10B147.
Nothing is mentioned regarding the security flaw detected in previous days which allows the blocking code to be bypassed, so we will have to test if this vulnerability has been solved or we will have to wait for a new update from Apple.
As always in these cases the users of jailbreak will have to wait until the members of Evasi0n Make it known if the exploit used to carry out this process in iOS 6.x is still available or Apple has already patched the security hole, since if they update they will lose the Jailbreak.
The update is now available for download from iTunes or via OTA.
More information - Apple will fix the bug with Exchange soon
The battery performance worsened even more
