I started a "set" (an album/folder/whatever) on my Flickr account for iPhone photos. I am just impressed at how good they turn out...and it's a cell phone! Granted, the lower the light, the worse they are, because the phone is going to max out the ISO and bottom out the shutter, so as long as it's broad daylight, it takes awesome shots. It's nice that it has a flash but the effects aren't usually that pleasant.

Check them out here. They are also all in my photostream. There aren't that many right now, but I have quite a few that I'll put up.
