I'll be getting the iPhone 4 next week. I can't wait. I've been waiting for the camera to get good enough for me to ditch my P&S's. I think the time has come. The 5MP, the auto-focus, tap to focus, the flash, the backlit sensor, the spacing of pixels, bigger chip, and of course the flash.
I'm not sure if those pictures are legit, but they claim the samples are untouched and straight from the iPhone.
