I found out how to do this for the ipad for those who are interested:
Instead of the code I used in my question, you would use:
$('body').bind( "touchstart", function(e){
$('div#extras').fadeTo('fast', 1);
});
&
$('body').bind( "touchend", function(e){
$('div#extras').delay(2000).fadeTo(1500, 0);
});
