Start up Google Mobile on your iPhone or iTouch and start typing in your favorite search, lets say for webmaster world. The app will suggest searches as you type. When webmaster world appears as a suggestion, click on it.
When the app displays the globe icon for Webmaster World, click and hold on the icon until the app flashes. You'll now notice that "webmaster world:" is placed in to the search field with the word "search" next to it. Just type what ever you want to find in webmaster world and Google will do a site search.
