As rumored, iOS 7 has a less skeuomorphic look, with a more flat design and lots of whites tinged with color. That doesn't mean, however, that the new iOS is free from gradient or panache. Instead, it's a more modern take on what makes iOS iOS.
Control Center
New in iOS 7 is a Control Center. It's an area that can be activated from within any app that brings control to Wi-Fi, brightness and other frequently accessed settings.
From Control Center you can access a flashlight, start a song, toggle AirPlay and more.
Multitasking
iOS 7 will bring better multitasking and background processing to all apps. It will monitor which apps you use frequently to help determine which ones need more full-functioning multitasking. When apps send push notifications, for instance, the phone will know to start to give that app background processing so that it will work more quickly and intuitively.
Apple has taken a major cue from webOS (RIP) and added full-previews of running apps for multitasking. No more tiny icons!
Safari
Safari for iOS 7 has a new look and feel — more similar to Chrome on iOS, we must say — including a new tabbed view. It also integrates with iCloud Keychain for password management.
The unified search menu, which was removed with iOS 3.0, is back. There is also access to shared links and the reading list improvements shown off with OS X Mavericks.
Tabs are now 3D and fully integrated with iCloud tabs. Users are no longer limited to eight tabs (hooray) and tabs can be reordered or removed with a swipe.
AirDrop
Apple is bringing OS X's AirDrop to iOS. AirDrop will let users share photos or files peer-to-peer with other iOS users who are nearby. "No bumping required."
AirDrop will only work on iOS devices running the latest wireless chipsets, meaning the iPhone 5, fourth generation iPad, iPad mini, and the latest iPod touch.
Photos and Camera
The Camera and Photo apps received a major overhaul. Not only is it easier to manage large numbers of photographs, users can now create Shared Photostreams — think group albums — into which other users can post photos as well as share with others.
Users can also share video with iCloud Photostreams in iOS 7.
Visually, the app looks similar to the latest Flickr redesign, is less focused on 4 x 4 grids of thumbnails, and offers users a better look at their photographs.
Siri
Siri has a new look and a new voice. Users can choose between male and female voices for Siri. Siri is also getting smarter: It will now pull in data from Twitter, Wikipedia and Bing.
iOS in the Car
Apple is going to bring iOS to the dashboard of your car. Support for iOS in the car will be coming to Honda, Mercedes, Nissan, Chevy, Kia, Volvo, Acura and others.
New App Store
The App Store has a new design and will show apps that are popular nearby, as well as apps popular with your friends. The best part? Your apps now update automatically.
Music and iTunes Radio
The Music app gets the same visual overhaul as the rest of the system but the big feature with music and iOS 7 is iTunes Radio. Think of it as a hybrid between Pandora and Songza, built into iOS.
Users can listen to theme-centric playlists or stations ("Songs for summer") or listen to artist-centric stations. And, like Last.fm, iTunes Radio keeps track of all the stuff you listen to across iTunes, Apple TV and on iOS 7.
It's free with ads, though iTunes Match subscribers get it free without ads.
