The Best Hidden Features in iOS 7

iOS 7 was released yesterday for beta testers and developers, and Heavy managed to get a hands-on look at the brand new operating system from Apple. Apple didn't announce 24 brand new features available only on iOS 7. Here are all the of the new 24 features in iOS 7:

- Enterprise single sign-on

- Chinese English bilingual dictionary

- Handwriting recognition for multiple Chinese characters

- Improved Mail search

- Streamline MDM enrollment

- Do Not Track option in Safari

But which are the best features? Here's what we think

FaceTime Audio

FaceTime Audio is definitely one of the best additions in iOS 7. Now, with FaceTime Audio, you can call your friends using Apple's FaceTime app, but you don't need to actually video chat with them. Instead, you can just talk to them like you would normally. What's the benefit? It'll help you preserve those constantly dwindling cell phone minutes. In addition, FaceTime Audio features free long-distance calling. As long as the other person has an iPhone as well, you can call them for free. Squeezing customers with cell phone minute plans, FaceTime Audio could prove to be quite a thorn in the side of carriers like AT&T, Verizon, and Sprint.
