I hope I can be forgiven for interpreting what you said as a statement, instead of as a true how-to question. My statement in reply was that this will take a few years to play out. Chrome's support doesn't make an immediate difference to you or to content publishers. Firefox doesn't support H.264 <video> either and has larger market share. So rest assured that no soldering gun is suddenly needed, and you can continue to use H.264 on your iPhone 4. Google's groundwork is supposed to come to fruition years from now, when you find an iPhone 5 or 6 already in your pocket.
