BGR claims AT&T has begun their yearly tradition of blocking employee holidays for the month of June in anticipation of the 4th generation iPhone (not iPhone 4G but possibly iPhone HD) launch.

A June block suggests a launch that could be as early as last year's June 17 iPhone 3GS affair, but is also consistent with previous years' late-June releases.

We've already seen some leaks -- and lots of fakes and mock ups -- so just consider this another sign of what we all know is coming -- iPhone 2010. And the crazy is sure to come with it!
