How limited is your viewport? I still have an old HTC Incredible 2 at home that I use for testing. Though not the smallest, it's only 320x533 (portrait). I'm used to a much larger viewport, and viewing forms with those dimensions are fine. Just ensure that your form fields aren't microscopic. Using the placeholder for explanation also removes the explanations when focusing on the field. A label is permanent.
