Since introducing iPhone OS 4 beta, Apple has kept a rigorous every-2-weeks-on-the-Tuesday update schedule through beta 4... until yesterday. Yesterday, the next Tuesday in line for beta, came and went with nary a beta 5 in sight.

Could be late, or it could be with WWDC 2010 less than a week away Apple is holding off to release the iPhone OS 4 GM (gold master) seed at the show? (Like they did last year for iPhone 3.0).

If you're stuck waiting, we've updated our iPhone OS 4 preview and feature walkthrough, so check that out and let us know what we're missing, and what you're still expecting!
