Apple just announced that iOS 7.0 will be available to the public on September 18. Now the new update has reached Gold Master (GM) status, which indicates it is out of beta and is on its last round of testing by developers before it is ready for public consumption. If you are a developer registered in Apple's iOS developer program, you can download the latest build right now though the Apple iOS Dev Center and test your app on the final version of iOS 7.The GM seed version is 11A465, and it has been released to developers. Most of the time, the GM version of iOS is what generally is sent out to users, but Apple may fix or tweak the build if they come across any bugs that need attention.
Registered developers can head over to developer.apple.com/programs/ios/ and sign in with your Apple ID. If you haven't registered for the developer program and wish to try out the latest version of iOS, you can register for an account ($99/year in the United States, or £60/year in the UK) and learn how to download and install the update on your iPhone, iPad or iPod Touch.
Apple hasn't added much in this newest release. Among the improvements are new colorful wallpapers, which match the colors of the newly announced iPhone 5C. There are also new ring and alert tones, with most of them being revamped versions of the classic tones. However the biggest change comes in the form of speed improvements over previous betas. Animations have been shortened to make the interface feel faster and snappier.

Non developers are advised to stay clear of downloading updates from anywhere other than Apple, as installing unauthorized updates could result in your device being permanently bricked and unusable. We have one more week to enjoy (or hate) the next version of Apple's mobile software, when it makes its way to all our devices.
