Here's how copy paste generally works on iPhone 3.0 Starting with an article on oleophobic coating of the new 3GS iPhone you highlight the word by invoking the magnifying class (finger hold). Then two markers show the marked text. Click on Copy which has appeared above the marked out text. Go to a google search, press and hold and paste will appear now (as you have something in the clipboard). Click on paste, Hit Google, and heres a definition on oleophobic.
