As the time comes closer to a possible iPhone launch the usual thing that signifies something is about to come out of the Apple camp is when the iPhone carrier stops its employees from taking any vacations, and according to an article over on the boy genius report that has now happened.

Word has it that AT&T has blocked employee vacations for the month of June and they say the only time the Big Blue does a straight block like that is when the iPhone is about to launch.

The guys over at the BGR also say they have confirmed this employee vacation blockage with multiple sources so it is reasonable to assume the block is indeed in effect.

So there it is; does this signify that the iPhone 4G will possibly launch in June rather than the rumoured July? Anything is possible as they say.
