Apple’s Developer Center has returned online following downtime, and iOS 7 beta 1 is officially available for registered developers. The software update was seeded for the iPhone 5, iPhone 4S and fifth-generation iPod touch, and the iPad version will follow in the coming weeks. Additionally, a new beta for Apple TV and a new version of Find My iPhone have been made available.
It is recommended that iOS users back up their iPhone or iPod touch using iCloud prior to installation, as this is pre-release software that is not guaranteed to be free of bugs or performance issues. iOS 7 beta testing will continue throughout this summer, ahead of a public release in the fall for iPhone 4, iPad 2, iPad mini and fifth-generation iPod touch or later.
