As noted by 9to5Mac, Apple has seeded iOS 6.1.3 beta 2 to developers. In line with our suspicions following the launches of iOS 6.1.1 and 6.1.2 emergency bug fixes released over the past two weeks, the original iOS 6.1.1 beta track has now been relabeled as iOS 6.1.3 with this second beta.

Release notes for the original beta version had indicated that it focused on Maps improvements for Japan, and Apple indicates that the beta now addresses the passcode lock bug publicized last week.

The release of the new beta comes just over two weeks after the release of the first beta version, although at least part of Apple’s team has undoubtedly been sidetracked by rushing the emergency Wi-Fi and Exchange bug fixes through development. A target date for a public release of iOS 6.1.3 is unknown.
