Apple Releases iOS 6.1.2 With Exchange Fix
Following various reports from last week, Apple has today released iOS 6.1.2. The software update, available for all devices running iOS 6.1, introduces a fix for Exchange that could have resulted in "increased network activity and reduced battery life".
The update is now available through iTunes and iOS' Software Update panel. It's not mentioned in the release notes, but -- based on some first tests I ran on my iPhone 5 -- it appears iOS 6.1.2 also fixes the passcode bug that was discovered last week (by following the steps to reproduce the old bug, the iPhone now simply gives a black screen/keypad instead of jumping to Phone/Contacts).
Update: I haven't been able to reproduce the bug on my iPhone 5, but Ars Technica's Andrew Cunningham says the bug is still unfixed in iOS 6.1.2.
