I saw a post on Ajaxian about how iPhone 3.0 might now include SquirrelFish Extreme so I did a quick and dirty using this. Here’s are the results (raw spreadsheet here).
iPhone 3.0 definitely has something, (whether it’s SquirrelFish or Nitro), but it’s 3x-10x faster than iPhone 2.2.
Update: Dear Apple, if this is against the NDA shoot me an email waynepan at me dot com

Please try it with this iPhone 3D JavaScript game (heavy use of HTML5 Canvas):

Keep GFX details on high but turn on the framerate display. Check the typical framerates during the game. Thank you.
