Apple appears to be cutting down on available vacation time for its AppleCare employees between September 15 and 28, a two week period encompassing the prospective September 20 release date for the iPhone 5S and 5C that was first leaked earlier this month. iOS 7 is also expected to be released that week. An internal document shared by AppleInsider reportedly shows the amount of time off available for AppleCare employees during the month of September, which appears to drop beginning on September 15.
