iPhone - rugged cases for hiking

I know at least a few of us have iPhones.
What cases have you found that provide good weather and shock protection for your iPhone whilst also providing good control of touch functions.
NB: I use the iBikeConsole on my hybrid bike and it can be easily detached from it's mount. It's great weather protection when on a Bike but probably not suitable for bush walking. See http://www.ibikeconsole.com/.
