Re: Heavy duty cell phone?
I had one of those rugged Verizon Casio phones for a while. Dropped it in a friend's beer, called it, left a voicemail then rinsed it off in the sink and called it again.
After I upgraded, we wanted to find out it's limits so we beat it up like we would a piece of gear. It's ultimate undoing was one drunken night when he decided to throw it at his brick bar as hard as he could and the outside screen shattered. Still works if needed, though.
Other than that, I've seen some other rugged cases on the market. I think one by a company called Ballistic or something. Otterbox isn't alone anymore, though, that's for sure.
