Using the iphone/ipod touch, when I browse a website page which has a form field for numeric data, like for zipcodes, it brings up the numeric keypad if it has pattern="[0-9]*" in the html.

Is there any way to to do this while browsing a web page on the pre? I know it's not a virtual keypad, but is there a way to get it so the num lock is on so the red button doesn't need to be pressed? Thanks for any ideas.
