You read it here second.
"A dubious source from a no-name site -- but it makes sense!" -- Gizmodo, covering without a trace of irony a rumor that iPhone 5 is coming to T-Mobile
iPhone 5 will go on sale in October, at least at AT&T.
Citing "one of our high-level AT&T sources," that an "AT&T Vice President has confirmed to several employees that the iPhone 5 is slated to launch in early October."
In the iOSsphere, "launch" is used interchangeably to mean "announcing a new product" and "making a new product available for purchase." Geller here means the latter.
