Yeah I would like one of those new ones. I have the 3GS and it's awesome but a flash on the camera along with more MPixels would be nice. You could get one by Christmas at least I would think you could but they are backordered right now. Heck I'm on this site more with my iPhone than my laptop since it's so easy.
I do use the calendar and sync it with outlook through iTunes. IMO this phone made all other smarts phones obsolete.
