AT&T has let the cat out of the bag yet again this year. A memo revealed this morning shows that AT&T is preparing for something, something big. The same thing happened last year before the launch of the original iPhone. Basically, the memo outlines that from June 15th to July 12th, all vacations should be rescheduled, and no new ones will be approved.

All rumors point to this time period as being the release date for the 3G iPhone. The question is though, is AT&T preparing for the launch of the new iPhone? The answer is quite possibly yes. This excerpt shows that they are talking about the same time last year, and that there is an opportunity to benefit from an exciting new product.

“Last year at this time we asked that all vacations be scheduled before June 15 or after July 15, to ensure adequate store staffing and to give everyone an equal opportunity to benefit from an exciting product launch. Thanks to your hard work, we experienced excellent sales during the mid-summer period. This year, the numbers you produced in 2007 will be hard to beat; but as a business, we must rise to the challenge, and make every effort to exceed last year’s sales results. Your management team is counting on you!”

The memo tells AT&T employees that they can expect there sales to soar. No kidding. We will all have to wait until WWDC though. AT&T may not be very good at keeping secrets, but I know another company starting with an ‘A’ that is.
