I'm looking for a case that'll do a great job of protecting my iphone, while at the same time not blocking signals. Basically I like to use iTrail and take the iphone on hikes. Of course, there's always the chance of a fall or something, so what I'd really like is a super hard case that could help with this. Frankly, i don't even care if I can't control anything while it's in the case, I just would like it protected. Any thoughts?
