Does anyone make a cell phone that is almost bulletproof? I am sick and tired of replacing cell phones because they get a little "damp" from the rain, or sweat, or get dropped, or whatever. Does anyone make a cell phone that is pretty durable, and has anyone tested one yet? I currently have T-Mobile, but contract is coming up for renewal, and have no problems with switching carriers at that time, if it means not replacing phones 2 or 3 times per year. Thanks!
