Apple has released the second developer beta of iOS 6.1.3, a minor point release to the mobile software suite that is said to include several bug fixes.
According to 9to5mac, the update features improvements to Apple Maps in Japan, and also addresses the lock screen bypass issue that was not resolved in the recently available iOS 6.1.2 update. The first beta of 6.1.3 only included the notes about Japan Maps enhancements, and thus the lock screen issue is a new addition to the developer build.
As usual with beta iOS software, the developer builds are only available to paying members of Apple’s official iOS Developer program at the Dev Center. Anyone can register for a free account, but beta releases are restricted to those paying yearly membership dues.
