3G iPhone in late June?

A similar memo went out last year around this time requesting that employees not take any vacations between June 15 and July 15, and this year those dates are June 15 and July 12 -- which seems suspiciously early, but that's what the man says. The memo cites "an exciting Summer Promotional Launch," which we're guessing doesn't refer to some new Motorola flip phone. Also telling is the fact that employees might be able to take some vacations later within that window when things die down a bit, which seems to imply that Apple could be aiming for a launch date right around the iPhone's one year anniversary of June 29th.
