Two weeks after Apple released the first beta version of iOS 7 following its unveiling at the company's Worldwide Developers Conference, Apple has just released a second beta for testing. The update is currently available through Apple's over-the-air updating system on iOS devices, and should be posted soon to the iOS Dev Center. iOS 7 is scheduled for release in the fall of this year, undoubtedly alongside new iOS hardware. Apple's iPhone, iPad, and iPad mini will all be due for updates in the latter portion of this year, and if past history is any indication iOS 7 should be made available to the public just a few days before the launch of the next-generation iPhone.
