I just got a Blackberry Passport and am trying to find a good case for it. I'd like something like an Otterbox Defender or Lifeproof case, since I work in dirty, dusty places. I have a lot of issues with my hands and am known for dropping things. I've looked through some of the threads on cases, but it looks like the companies that still make cases for the Passport mostly just make leather sleeves. Not things that'll actually protect the phone if I drop it on a concrete floor.
