I was happy to find that an Otterbox 2000 case that I had around is a perfect fit for the 770. This thing is bombproof: hard plastic lined with closed cell foam and has an o-ring to keep out H20. A few index cards or a screen cleaning cloth can be carried around to make the 770 as thick as the interior and the other two dimensions are right on the money (with the silver Nokia screen protector). $18. My 770 now bounces around in my messenger bag and motorcycle saddlebags. No worries, mate.
