iPhone OS 3.0 is riddled with hints that video recording is on the way, and the latest is is this supposed screenshot of a revised camera app with a video toggle. MacRumors says it comes up when certain config files are edited to make it seem like a video camera is present, but it's not clear exactly what steps have to be taken, so we're treating this one cautiously until we can confirm it. Other secret features buried in the plists are said to include "auto-focus camera," "voice control," and "magnetometer," which is assumed to be a compass. Yep, all stuff we'd expect from an iPhone revision around, say, June, but nothing earth-shattering -- and if the video features are as mediocre as the current iPhone camera, we don't think the Flips of this world have too much to worry about.
Update:Boy Genius Report has scored some other 3.0-culled goodies, including what appears to be voice dialing ("Voice Control" as they're calling it), a digital battery strength readout, and further evidence of video support. Beta 3, where are you?
