An internal email addressed to AT&T employees notes that the company encourages its staff to schedule their vacations before June 15 and after July 15. This is to ensure that during the said time period they are properly staffed to take advantage of what could be their "biggest selling period" in a few years.

While we all know that Apple's iPhone is set to debut this June, at least now we have hints at a more specific window for the handheld's release.

While Apple has noted that the iPhone is on track to see a late June release and this email gives us a narrower window, others have even gone as far as to speculate that the handheld will indeed be launched on the 15th itself.

Let us know what you think of this after you check out that alleged "AT&T employee email" that's currently circulating the Internet.

As previously announced, Apple and AT&T will soon debut the iPhone,
which combines a mobile phone, a widescreen iPod with touch controls, and
breakthrough internet communications into one small and lightweight
handheld device.  The new AT&T has a multiyear, exclusive agreement to
provide U.S. service for the iPhone.

To ensure proper staffing during the product launch period, Sales personnel
planning to take approved time off are encouraged to schedule their
vacations before June 15 or after July 15 to participate in the iPhone
launch.

Previously approved vacation will be allowed where voluntary rescheduling
is not feasible

No additional vacation requests will be approved during the launch period
(6/15 Â? 7/15).

I want to thank you in advance for your understanding as this is likely to
be the biggest selling period we have seen in a few years.

Happy Selling,
