However now that Apple has had time to sort things out iOS 7 beta 2 (build 11A4400f) is now available to all devices supported by the iOS 7 update.
The iOS 7.0 beta 2 has several new features and improvements including:
- Voice Notes app is back
- Messages now shows message sending properly, and delivered and read notifications are properly spaced.
- New Exchange logo in Mail
- Voicemail now works
- Traffic option in Notification Center
- iTunes & App Store settings are now combined in Settings
- Much more responsive in general
- More easy to read notification drawer, lighter effects, and better close button.
- Updated opacity / color in Folders background
- Safari UI enhancements
- Stronger Wi-Fi password suggestions for Personal Hotspot
So if you are a registered developer 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.
Along with the iOS beta, Apple has also released Xcode 5 Developer Preview 2 and a new Apple TV 5.4 beta. There are still several enhancements needed to ready iOS 7 for public use, but this beta release shows that Apple is well on their way.
