Apple has released iOS 6.1.3 beta 2 to developers for iPhone, iPad, and iPod touch. This is notably the second version of the one-time “6.1.1” beta, containing the same Japanese-focused enhancements to the Maps application; Apple changed the name after releasing 6.1.1 and 6.1.2 patches to fix bugs with iOS 6.1. The beta is available through Apple’s developer portal. [via 9to5Mac]
