Version 6.0.1 fixes several issues, including display problems that showed horizontal lines across the keyboard, a bug that caused the camera's flash to be unreliable and not go off occasionally, as well as a flaw that prevented iPhone 5 users from installing software updates via Wi-Fi connections.
Additionally, Apple also consolidated the "Use Cellular Data" switch in iTunes Match, and fixed the Passcode Lock bug. Given the number of problems of iOS 6, the release of 6.0.1 shortly after the launch of the OS is not surprising. However, 6.0.1 appears to have some problems as well. Several users are reporting that iOS 6.0.1 does not play well with the Facebook app and calls for an updated version of this application.
Apple also released iOS 6.1 beta to developers. Build number 10B5095f comes with subtle changes to the Safari browser, enhancements for Passbook as well as the ability to integrate Apple's new Maps service in third-party apps.
