Waterproof/shockproof phone
I just upgraded my Verizon phone to a new waterproof, shockproof, and sand/dirtproof phone. It can even be dunked up to 30 feet under water (and record video underwater and pictures with a 2 megapixel camera). It has a plastic loop on it to secure it to something with a small caribeener. It even has 4 split stop watches accurate to within 1/100 of a second. It also has an LED flashlight. It seems like a worthwhile investment for the rigors of BASE jumping. http://estore.vzwshop.com/gzone/
