A Mac|Life tipster sent us a story about his recent trip to an AT&T Corporate store in Southern California.
A customer service rep at the store told our tipster that AT&T has a Blackout date for the iPhone in June. Once a blackout date is set, AT&T won't recieve shipments of the device from that date forward.
The CSR added that AT&T was planning on subsidizing the iPhone similar to other mobile devices sold by the mobile carrier.
I'm not sure how much information AT&T shares with its sales staff, but some of the info corresponds with recent rumors of iPhone subsidies and AT&T staff being asked to postpone vacation time.
As with all rumors, we'll just have to wait and see.
