David Pogue of the New York Times (via Macrumors) managed to wrangle some information from this year's Macworld 2009 Keynote Speaker, Apple's Senior Vice-President of Marketing, Phill Schiller, confirming what's gone before -- and what we sort of expected about the iPhone product cycle:

...the holiday season (Novemberish), the educational buying season (late summer), the iPod product cycle (October), the iLife development cycle (usually March), the iPhone cycle (June).

So iPhone 3.0 this summer?
