I was looking at a youtube video today with safari and has the HQ option turned on, the video seemed to be playing at 360p or 480p. I tried it on both wifi and 3G and the quality is about the same. I tried it on jasmine but it was still the same. I went to download the youtube iOS app. It seemed sharper because of the double letter boxing(if I said it correctly) and made the video smaller. I used my mothers galaxy s3 and it seemed to play very sharp at 720p. Is it just me or does this apply to all the iPhones?
