I am hoping to pick up a Verizon iPhone 4 this week. I plan on bringing it with me while running - perfect for music, GPS, and phone for emergency! When I usually run, I hold my iPod Classic or iPod Touch in a hand. Both of those are well protected. I'm looking for a good case for running, but that is also nice to use everyday at work, etc. too. I did a search here, but saw mostly armband cases. I know the Otter skin(?) ones are supposed to be good, as are the Griffin ones. I am so far leaning toward the Griffin Survivor, but it seems a bit too bulky for carrying around at work, etc. Any recommendations on good running / everyday cases?
