With a few lines of code, it seems, at least one of the specs of the next iPhone is settled. According to video capture presets tucked away in the iPhone SDK, 720p recording is in the cards.
The evidence is fairly clear:
These presets, buried in the iPhone SDK, don't guarantee HD video capture. But the iPhone ecosystem is contained enough that any reference to HD video anywhere is significant. I mean, why would there be a stray reference? What would it once have referred to?
More to the point, this is something that's been talked about before. The next iPhone is suspected to have an upgraded camera—we know it will have a flash—and 720p has been explicitly mentioned in rumors before. Also, it's currently on the market in a handful of other phones, so it'd be kind of a disappointment if the next iPhone didn't ship with it. [Macrumors]
