T-Mobile has implemented vacation blackout dates between September 20 and 22, reports TmoNews, potentially confirming a prospective September 20 release date for the iPhone 5S and 5C that was first leaked earlier this month by Japanese business newspaper Nikkei. During the blackout period, employees will be unable to take vacation time to ensure that T-Mobile has adequate staff on hand for a large release event. Similar blackouts have been instituted for the launch of previous iPhone models and other high-profile products.
