It's hard to know which side you're arguing for. The iPhone is likely faster, there are a plethora of apps that burst shoot, it can switch to video in a moment and it's faster to start taking photos. By the time the SLR has been set to P mode and auto iso etc e iPhone would have already shot the photos and uploaded them to the server.

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.

At least for stills there's simply no way the iPhone is faster, burst mode apps or not. (I speak as a frequent user of both DSLRs and iphones.) The ability to zoom and crop means you can get shots with a DSLR than an iPhone could almost never get (barring ungainly tricks like shooting through binoculars) and you can't freeze action.

Nooope, it's not even close--the iPhone is slow, inflexible, and poor-performing compared to a pro DSLR hooked to a 24-70 f/2.8 or 70-200 f/2.8 zoom. Consumer DSLRs are kind of pokey, but the pro models go from "off" to "shoot" in a fraction of a second, with no perceptible delay between hitting the shutter button and an exposure. There is no faffing about with P mode or the like (only someone who doesn't know how to use his camera would be caught out doing this).

The iPhone does have an advantage in network connectivity, but it's comparatively unlikely to capture the couple of moments worth saving.

An iPhone is never faster than a pro DSLR. From hip to eye, power on and shooting in under a second. There's a reason the power switch is part of the shutter.
