Apple has just released the sixth beta version of iOS 7 to developers for testing purposes. The update is available as an over-the-air update to existing beta testers and it can also be downloaded via Apple's Developer Center. It was reported earlier today that Beta 6 would be released next week, roughly two weeks after the release of Beta 5; however, the odd timing of this release -- Apple traditionally releases new iOS betas to developers on Monday mornings -- along with its small size, only 13.5MB on an iPhone 5, suggests that it could be some kind of urgent bug fix. The new beta arrives as build 11A4449d, and comes a little more than week
