More than three weeks after releasing the second iOS 7.1 beta in December, Apple (NASDAQ:AAPL) on Tuesday seeded the third beta of iOS 7.1 to its registered developers. The new beta is identified as “Build 11D5127c,” and is now available to download from Apple’s developer website or as an over-the-air update.

According to Apple, the iOS 7.1 beta 3 includes both bug fixes and other significant changes to the iOS 7 platform. The update fixes an issue in iOS 7.1 that had caused problems when listening to audiobooks on an iPhone, iPad or iPod touch. The latest beta also includes fixes for iCloud account setup with iCloud Keychain.

Apple has also informed developers that some of the known issues still remain with the iOS beta 3. For example, 32-bit Bluetooth applications on 64-bit devices, such as the iPhone 5s or latest iPads, do not work properly. In addition, an error is also said to remain with the Messages app, causing an iMessage send failure immediately after sending, Apple Insider reported.

Check out more of the key changes introduced with the iOS 7.1 beta 3 here:

- Apple has tweaked the standard keyboard slightly by adding boldness to the font and with a new design to the shift and delete keys.
