Apple has seeded its iOS 6.1.3 beta to developers, which patches the lock screen bug and adds improvements to Maps data in Japan, according to a report by 9to5 Mac.
The release follows previously unsuccessful updates; first with the release of iOS 6.1.1 on February 6 to developers, which was then made available to iPhone 4S users to fix a 3G bug. iOS 6.1.2 was then issued to all iOS users to address a Microsoft Exchange issue that was causing significant battery drain.
Now, reports 9to5 Mac, Apple’s iOS6.1.3 beta will patch the lock screen security bug that granted unauthorised entry to a locked iPhone, with access to contacts and photos. In addition, the update will deliver enhancements for Maps data in Japan, including improved toll road information and directions.
It’s not known when the public version of iOS 6.1.3 will be released.
