Take someone with a DSLR on their hip and someone with an iPhone in their pocket and see who can get the shots you want. Subjects don't stand still and they won't wait for you to be ready.
The wifi/cell part of the photo is not to be ignored, GPS stamped images uploaded in seconds. The SLR can't compete yet. In a year or two when wifi is prevalent on SLR cameras, maybe, but for the moment is speed counts the iPhone will win for photos and video.
The iPhone does have an advantage in network connectivity, but it's comparatively unlikely to capture the couple of moments worth saving.
