AT&T is telling employees not to take holidays in June, according to Boy Genius Report. You know what that means: iPhone 4 is right on schedule.
The only time AT&T schedules these kinds of mandatory work periods, apparently, is for the increased traffic associated with iPhone launches. And while there had been some rumours about an April release, the smart money (and historical precedent) have always pointed to a mid-June/early July release. Time to start calculating how many months from then I'll be eligible for an upgrade. [BGR]
