Oh yeah I forgot .
Personally I don't rate waterproof cases.
Most of the time they easily break, or render all the ports inaccessible (thereby meaning you'll be taking it in and out to charge so are less likely to remember EVERY time, any time you forget it is not waterproof!), or really bulky so phone cannot sit comfortably in pocket(I'm looking at you otterbox) and often make speaker and one or both sides of phone calls muffled and weakens strength of 3g/GPS/general phone signal.
The best that I have seen is LIFEPROOF range but still could not honestly recommend it.
