The new iPhone could be arriving on Sept. 20, if a new batch of rumors is to be believed. 

According to CNET, T-Mobile employees are being barred from taking any vacation days Sept. 20 through 22. This is the same weekend that Apple's new iPhones are expected to go on sale. 

Unnamed sources told TmoNews that the blackout for employees was most likely related to the new iPhone. But when contacted, a T-Mobile spokesperson refused to comment on the report -- only calling it a rumor. 

The launch time for past iPhones aligns with the timing of the reported blackout dates as well, leaving many to speculate that these sources may be correct regarding this latest release date. 

The rumored announcement date for the new iPhone is Sept. 10. Apple has previously released every iPhone -- except the iPhone 4 -- on a Friday. And the iPhone 4s and iPhone 5 were both released on the second Friday following their announcements. So if Apple follows the pattern, it seems Sept. 20 may usher in the newest iPhone handset. 

The Wall Street Journal reports that Apple's Asian manufacturing partner Foxconn has already started production on two different models of iPhones in preparation for a September launch.
