I've searched a bit and can't seem to find a product to plug (cleanly lol) the headphone jack. I never use it (use the dock adapter for my HT and car for sound), and would like to keep the headphone jack free from dirt/water/whatever =).

Anyone out there hear of one or have any ideas for substitutes? Some sort of silicon plug would be ideal, as long as you could get it out eventually (a snug fit would be a plus, as would sitting flush with the top of the phone).

Am I crazy or has anyone else thought of this? LOL
