I-Phone/Smartphone rig

Hey guys, had to upgrade to a smart-phone (iPhone) and am wondering if there are any good cases that are recommended for use on the yak? Basically something that I can still use the camera and phone with without getting it wet and voiding the warranty? Apparently they now have a moisture sensor that will void the warranty if it senses any moisture.

Any info is greatly appreciated

Thanks.

My recommendation... from a IT guy.

I use the otter box,

not completely water proof ect.. but takes a beating

For the cost of replacing an iPhone, you can get a darn nice camera.
