1.  Isn't there a javascript event for ondoubleclick?  Peraps Safari
will do strange things to it.
2.  There should also be some padding around form elements in general
to make it easier to click on the one you want.  Also a screen resize
event might get fired due to the keyboard popping up.  This means we
might want to have a event attached to each form element to handle it
special.
3.  The more I think about it I hope there is a nice way to make an
iPhone .css sheet and load it specifically.
