T-Mobile document leaks potential iPhone 5 release date

Could T-Mobile have confirmed a piece of the Apple iPhone puzzle via leaked information about the wireless service provider's September sales agenda?

In an image acquired by unofficial T-Mobile blog TmoNews, the company seems to be prepping its employees to "sell against the iPhone," starting on 21 September – the same date rumoured as the release date for the so-called iPhone 5.

The document, which also includes details about a 9 September kick-off meeting, discusses a Grab & Go suite that will be available on T-Mobile's electronic training system beginning on Friday 21 September.

But there's an alternative explanation for the memo. The carrier doesn't currently sell the iPhone and TmoNews suggested the memo indicates T-Mobile won't be selling the new iPhone, either.

"Perhaps it's coincidence, but we can't envision a scenario in which T-Mobile would prepare their employees to sell against a product they are about to receive," the blog noted.

If so, without an inside track on Apple's planning, T-Mobile itself may simply be operating based on the pervasive rumours of a 21 September launch to prep staff for what's likely to be another onslaught of iPhone competition.

Rumours began circulating last month that Apple will debut its next-gen device at a special event on 12 September, then release the phone nine days later. The firm has not confirmed the reports, leaving the world to count down the next 15 days in anticipation.

Last week, a Verizon employee told TechCrunch that the wireless company has blacked-out vacation time between 21 September and 30 September –in line with the possible release of a new iPhone, which past history suggests will fill stores with excited customers.
