Remember how Apple said during Macworld Keynote how they were announcing the iPhone early because they didn't want people to find out via the FCC? Well, apparently Apple already filed a few things before the Keynote and asked the FCC to keep them quiet. This letter from Apple dated October 12 requested the FCC to keep various diagrams and photos hush hush until June 15, which coincidentally is the last day of WWDC.
So what's the deal? Is Jobs going to climb up on stage at WWDC, show us all the unannounced/undeveloped features of the iPhone and announce that it's "available now"? We're willing to bet he is.
