Designing for iPhone
Some interesting things you can do:
two finger drag for iFrames
Don't think windows - think Viewports (imaginary windows)
Don't use empty div tags - because they will scale with the page
Optimum hit area for link buttons is 80 pixels.. yes, folks 80 pixels.
I have played around and 18 pt font works very nicely.
For native iPhone web pages use
meta name="viewport" which will tell the browser what to expect.
Optimum page width 480 - max scale 1/3 for horizontal orientation.
For video always use reference movies.
H264 with AAC
which mean you make 3 reference copies of the movie.
Tooltips don't work
mouse down doesn't work
Always use a iphone specific css file .
more as I continue to mess around
