Apple has today seeded the latest version of the next substantial update to iOS 6 to registered members of the iOS developer program. The company today released the third beta of iOS 6.1 for Developer testing (via MacRumors), and it is available for download now (as long as you are a paid up Apple Developer). This latest update brings iOS 6.1 closer to release (for comparison’s sake, the original iOS 6 software went through four Developer betas).
The new update contains some significant updates related to the use of Passbook and how boarding passes are stored and used within the app. The update also brings some fixes for Safari and some new updates to allow the use of Apple mapping technologies in third party apps. The previous beta was seeded on November 12, so this update is only three weeks after the last one.
