AT&T ramps up for 3G iPhone sales

An internal memo within AT&T told itsemployee’s that they can’t take any time off from work next month because of an anticipated “heavy selling period” resulting from a Summer Promotional Launch.  AT&T is blocking off June 15th to July 12th this summer for the new product launch.  This of course is speculation at this point but as The Reg said in the article, what else could this be?  Especially since rumors have surfaced about a new 3G iPhone being released this summer.
