Apple Insider reports that Apple has released the third beta of iOS 6.1 to the developers

The update is available through Software Update in the iOS Settings application. People familiar with the software said it is identified as build "10B5117b." It arrives three weeks after the second beta was issued.

One person testing the software shared with AppleInsider that users are now asked to enter security questions for iCloud once their device boots up. This feature was not in previous betas of iOS 6.1.

The iOS 6.1 beta is compatible with the fourth-, third- and second-generation iPad, iPad mini, iPhone 5, iPhone 4S, iPhone 4, iPhone 3GS, and the fifth- and fourth-generation iPod touch. Apple informed developers that the beta "contains bug fixes and improvements."
