For some reason, I can't select just the script on that page when I'm on the iPad, so I created a standalone page that contains only the script itself. You can open that page, select all that text, and paste it into your bookmark on Mobile Safari.
Full instructions for creating the bookmark can be found on the original post.
And many thanks to Greg for all the work he's done on this. We are all in your debt, Greg! (Follow or thank Greg at his blog or his Twitter.)
