Apple will release iOS 7 for existing iPhone, iPad and iPod touch owners on Sept. 18, but registered developers can download the GM (or gold master) right now.
The guys over at TechSmartt released a video overview of some of the new changes, including brand new wallpapers, ringtones and notification sounds.

We've watched the progression of iOS 7 in its beta stages over the last few months, so it's satisfying to see the final product in action. I just installed the iOS 7 GM on my suite of test devices and I agree with TechSmartt's assessment: iOS 7 is smooth, fast and feels complete.
We'll have a more in-depth iOS 7 review when it officially lands next week, but until then, let us know what you're most looking forward to in the new OS.
From the moment iOS 7 loads, its clear this is different. The linen that infused iOS 5 and iOS 6 is gone, replaced with white and thin sans serif typography.
While white is a predominant theme in iOS 7, this is not a monochrome OS. Color accents are almost always visible.
For the first time since the original iPhone, the overall look and icon structure of iOS is now new and fresh.
The wallpaper can now be dynamic or static. Dynamic wallpaper is similar to the animated wallpaper in Android, except it doesn't interact with your finger. The default wallpaper is static.
Mail has received a full revamp to both its main view and the compose screen.
Flickr and Vimeo join Facebook and Twitter as built-in services.
Swiping up from the bottom brings up the Control Center. This is an easy way to access your most used settings, including WiFi, audio, brightness and quick access to alarm, a calculator, camera and flashlight.
Meanwhile, photos can now store more items and span pages.
The new camera interface has a number of options built-in. Swiping across the bottom brings up options for the standard camera or the video camera.
There is a new square mode on the camera, perfect for Instagram. The panorama mode is still here too.
Apple also has its own filters built-into iOS 7. Rather than simply applying a filter in post, these filters are actually real-time and you can look through the viewfinder in that filter before taking a shot.
The Stocks app looks totally fresh. Notes also has a new coat of paint. The texture is still there but the yellow lined paper and Marker Felt are a thing of the past.
iTunes and the App Store both have new designs. Additionally, Apple has introduced a new Wish List feature on mobile, making it easy for users to save an app to buy later.
The App Store structure is still the same but the look is more fresh. In addition to the general charts, users can also check to see what apps are popular in their area.
A new share button shows off what you can do with an app which includes AirDrop and adding it to a wishlist.
Both look fresh.
The Lock screen no longer has anything to slide to unlock, just swipe to the right.
You can choose to make Control Center available at the lock screen or not.
Pulling down from the top still brings up notifications, only now without linen and with a history.
The weather app is beautiful and animated.
Reminders is now more robust in its appearance. There are different groups of reminders, not just lists.
The new reminder screen also has a refined look. It still has texture, but the lines are less bold.
The compass looks totally new and totally great.
Double tapping home brings up full screen previews of various apps. Scroll back and forth and see previews of your apps in real-time.
Some might say this is copying Window Phone, but really, this look was pioneered by Palm with the late, great, webOS.
The dialer and the iMessage interface follow the new trends of being bright and with lots fo color.
Notifications pop-up in dark now, not white.
The calendar is de-leathered and has a very Google+ look.
The calendar gets a proper inbox for incoming invitations.
Apple Maps has toned down some of its textures but the basic app looks very similar.
The directions page in Maps has been rebuilt and it looks much more sleek.
The calculator still pays homage to the great HP calculators of the 70s, but with fewer bevels.
As for the clock, gone is that patent-infringing world clock look.
Check out the 3D effect when picking a time.
The timer is totally new too. This is what one of the standard settings pages looks like.
The bookmarks section for Safari is texture free but full of color.
The search and URL omnibox makes a glorious return (it was separated with iOS 3 back in 2009).
The whole look of this browser would look equally at home at Mountain View as it does in Cupertino.
Typing in a URL or string of text offers up real-time suggestions for an address or search query.
The thin bar at the top of the screen indicates page load progress.
It's like Cover Flow, but vertical!
FaceTime can now do audio calls!
