iPhone 5S release date could be set for September 20th as T-Mobile has issued a vacation blackout for its employees starting 20th and ending 22nd. Apple is widely rumored to hold iPhone 5S media event on September 10th so its possible that 20th may in-fact be the release date for the new iPhone.
Apple’s carrier partners usually issue blackout dates in order to make sure that they have maximum workforce during the first week of the launch of a major product. iPhone launch day has traditionally witnessed long queues and such blackout dates have been reported in the past with other carriers as well.
This year Apple is expected to introduce two iPhone 5S and iPhone 5C. While iPhone 5S will be the flagship product for 2013, iPhone 5C will be a more economical model geared towards pre-paid users and the Asian market.
iPhone 5S is widely reported to feature dual-led flash, A7 processor expected to be 31% faster, new fingerprint sensor and advanced camera software supported by new motion sensors. The overall design of the new iPhone will remain the same as the current gen phone.
If previous years launch is any indication then September 20th launch of iPhone 5S in the United States could be followed by the second round of countries about two weeks later.
