I've always used the Ocean Pacific Cell Suits. They are made out of neoprene, the same material used in wet suits. It's spongy, durable, and can take a 20 foot fall off of a scissor lift or a 3-story staircase fall. Not to mention... neoprene is virtually water resistant. Don't go dunking your phone in the nearest 5-gallon paint bukcet full of water... it still has the holes necessary for the mic, earpiece, headset, bottom connector, etc. You can find these in any NEXTEL Retail Store custom made for your specific model.
