TUAW reader jadam asks if someone would please code up a bookmarklet that allows you to paste into website fields. It's a bit of a hack but I've put together this bookmarklet that you can sync to your iPhone and paste a pre-defined phrase into Safari.
This version pastes the word TUAW but you can easily replace TUAW (defined by "replacetext") with any other phrase. The bookmarklet iterates through all the form fields on your page, allowing you to select where to paste. You're welcome, jadam!
