Just received the OtterBox Commuter and a armband by Tune Belt. All via Amazon. The case is really nice looking! I first tried the Defender version, and disliked the covers over the outlets, and the overall feel. The commuter is slimmed down, fits nicely in my pocket. Also it makes hitting the power button and volume rocker MUCH easier!! Only sucky thing was the screen protector that came with it has a little exterior paper tab that doesn't like to come off, and is now a gooey mess. The armband originally was for my wife's Iphone 4S which is housed in a Otterbox Defender. She didnt like how snug it was in the case! ok... Mine now!!!! The Rezound w/ case fits GREAT!
