Apple just released iOS 7 Beta 6 to the developers. The update is considerably small and it just fixes an iTunes in the cloud issue on iOS devices.
Apple has been working so hard to fix the bugs in its latest and the biggest iteration of iOS, the iOS 7. The OS is currently in beta, and is available for the developers to test their apps on the new operating system for Apple’s mobile devices. Today, the 6th beta of iOS 7 fixes an issue with iTunes in the cloud, and that is pretty much it with this update.
The update is available via OTA on your iOS device running iOS 7. The size of the update, which would regularly be around 200MB, is now just 12-25MB, since it is more of a fix to iTunes in the cloud rather than a major bug fix update.
You can get the update by navigating to Settings > General > Software Update. The final version of iOS is expected to arrive as early as September, instead of October. There are also reports that the Gold Master build of iOS will be available in the coming weeks.
