We've received yet another bit of evidence confirming the next iPhone's September 21 launch. According to an AT&T sales rep, AT&T staff has been given a vacation blackout from September 21 to September 30, just like Verizon employees. Our source also mentioned that blue carrier employees are undergoing training for an "iconic release."
Last week the site reported that a Verizon source had confirmed a release date of September 21th for the next generation iPhone. Apple is expected to unveil the device on September 12th.
