Earlier this month, Apple seeded the first beta of iOS 6.1 to developers that included new features allowing developers to integrate iOS Maps into their applications, as well as fixes for boarding passes in Passbook as well as changes in Safari. Now, Apple has seeded a second beta of iOS 6.1 to developers with a build number of 10B5105c, as opposed to the build number of 10B5095f for the first beta of iOS 6.1. it is unclear what changes the second beta has brought to the update.
It is likely stability improvements for the iOS Maps and Passbook features. It is unclear exactly when Apple will release iOS 6.1 to the public but Apple will likely identify other bugs and include them in the final update, perhaps even releasing another beta before finally releasing it.
Alongside the second beta of iOS 6.1, Apple also released a beta of the Apple TV software, as well as Xcode 4.6 Developer Preview 2. Developers who are registered to receive these updates can go and download the beta software through Apple’s Developer page.
