I'd be really glad if someone could try that out on their device. So far it has been reported to play correctly in QuickTime under Mac OS. Unfortunately there was a misunderstanding between me and the person who tested it, where I thought that he had an AppleTV. However he said that as Apple claims, that whatever plays in QT works in iTunes and AppleTV too, so I'll just take his word for it then...
I can tell you yes without even trying it. From how I understand it, mp4 files store a timestamp with each frame, as opposed to having a list of framerates.

Framerate is actually a derived quantity for mp4s, and not stored directly anywhere (except for the header, but that's mainly for show, and isn't used in playback).
