True, although hopefuly that'll just get exposed to javascript. In the same way that the orientation of the iPhone (portrait/landscape) is exposed to javascript.
Yeah, that is what I meant by browser API. I have no experience with mobile browsers yet - I guess you can't install plugins for them, as with the desktop ones?
What can you do in a native app that you can't do with some javascript and a pretty webapp these days :/
The days of native apps is ending. On the desktop, on mobile phones, everywhere.
