Apple has already announced that they will be aiming to fix the Exchange battery drain and the major Passcode bypass problem. However, the fix will come in a brand new iOS 6.1.2 patch.
According to iDB, a German site named iFun is reporting that Apple won’t just release a basic hotfix, but will actually address the major issues for iOS 6.1.1 by simply releasing iOS 6.1.2.
The 6.1.2 release is being rumored to have come from the same source who revealed that iOS 6.1.1 would be arriving, so there’s a lot of weight behind the claims.
