The iOS 7 features rumor mill is slowly escalating into fever pitch as developers scramble to learn about the newest software from Apple. Rob LeFebvre of the blog Cult of Mac, unveiled five more hidden features in iOS 7 Beta.

Some of these features include Audio-Only Facetime Calls, Timestamps for iMessages, the new AppStore WishList feature, new Today View on Lock Screen, and ability to add custom station to iTunes Radio.

The bells and whistles on the new iOS 7 has helped propel the beta software to gain mass adoption rates never before seen in an Apple operating system. According to mobile publishing firm Onswipe, the adoption of Apple’s iOS 7 beta is moving faster than any previous versions. iOS 7 involved a major design change, something that hasn’t happened since the debut of Apple’s mobile operating system in 2007. It features a new Notification Center, Control Center, and has been redesigned for multitasking.

The beta release of iOS 6 on June 11, 2102 brought in 0.25% mobile device users that visited Onswipe’s site using the new beta 6. Now, as of July 1, OS7 beta users are bringing in 0.46% traffic to Onswipe’s sites.

The 0.77% of iPhone users that visited the various Onswipe’s sites are using iOS7 and 0.28% of iPad users are using the operating system. Last year, for iOS 6 Beta, 0.19% of iPad users that visited and 0.38% of iPhone users that visited were running the beta iOS6.

Mac Rumors reports: “The takeaways from Onswipe, according to CEO Jason Baptiste, are that developers are around twice as excited about iOS 7 as they were about iOS 6, and that they're spending more time getting ready for the big changes coming in the new version of Apple's mobile OS in order to have everything nice and tidy for the consumer launch coming this fall.”

iOS 7 is currently only available for developers, but is expected to be released this September.

Numerous speculations have pointed out to the possibility of iOS 7 being simultaneously released with the iPhone 5s.
