In the index.php file of the mobile_iphone template, I modified:
<meta name="viewport" content="width=device-width, initial-scale=1, minimum-scale=1, maximum-scale=1, user-scalable=no">
to be
<meta name="viewport" content="width=device-width, initial-scale=1">
This change allows the user to use the pinch zoom method to zoom out or in.
This has essentially resolved the issue although I'm still trying to find a better method for showing large amounts of data on a small screen.
