TacomaSailor,

I'm not sure I follow how an Otterbox traps moisture in the case. My Otterbox is not water proof, and especially since I removed the plastic screen cover that it came with, its not airtight or water tight. What you said makes sense for a totally waterproof case, but my concern is how to keep sweat, spit, etc. from getting into the phone if I take your technician's advice and ride with the phone exposed to atmospheric conditions.
