Also, in general: fantastic, fantastic phone. The screen reminds me very much of the high-res move on Palm in 2001/2, or on Windows Mobile in 2005 (and then again on smartphones in 2007-8 or so); even after an hour or so of use you really can't go back to the old iPhones / iPods, in fact even the iPad's screen starts to look jagged and blurry. Performance is wonderful, form factor very sexy though it takes a little getting used to after the 3G/3GS' rounded back (the bumper helps a lot comfort-wise, though I wouldn't pay Apple $30 for one when you'll be able to get them anywhere for $10 in a few weeks), and unlike on the iPad most non-optimized apps still seem to look pretty darn good. Pretty much the best Pleco device ever, though I did discover a couple of icons that weren't showing up correctly as high-res (now fixed for 2.1.2), and there are a few minor iOS 4 issues (deleting user dictionaries, e.g.) we also need to fix.
The camera could be borderline revolutionary, actually; for still images it's certainly in the upper echelon of smartphones, but the video recorder is really first-rate, and having millions of people carrying high-definition video recorders around with them all the time is going to do wonders for citizen journalism. Somebody needs to develop an app that records video, automatically uploads it in the background (using iOS4's task completion feature), and doesn't have a cancel button (or even a progress indicator to show that it's uploading) - that way people can record other people doing bad things and know that even if their camera is confiscated it's likely their video will still get out (assuming the bouncer / security guard / police officer / whatever who confiscates it isn't tech-savvy enough to recognize the need to / figure out how to kill a background app). And given the societal benefits, they probably ought to release said app for free. (any takers?)
