So, the 3GS can do some pretty hard-core video. Not through iTunes, but if you put a file online and go via mobile safari or the iDisk app the quicktime player service will play it just fine. How hard core? Well, I turned on a bunch of handbrake options the ATV chokes at and got 720*544 (anamorphic - effective resolution 1009*544) @2.8Mbit. I don't have a composite cable to test it on, though, so I guess my question is... does that output properly to a HDTV? I mean, is the TV getting a full-fat 1000+ pixel wide image? Just, it honestly wouldn't surprise me if the phone took that video, rendered it to 640*480 and then sent that to the TV. Apple love to make odd decisions like that, after all. If it does work "properly" I'd love to use my 3GS as a mini-Apple-TV with the composite cable, the remote-control-dock thingy and an app like Air Video.
