Passage Three

　　Most cell phones hate water. Get a few drops under the case, and that horrible little wetness indicator next to the battery goes red. Next thing you know, your phone doesn't work, and your carrier won't replace it. So bringing your phone to the beach can be a bad idea. The good news is that there are three types of cell phones built specifically for active fun.

　　The Casio Exilim C721 on Verizon Wireless is the ultimate summer phone. That is because it also doubles as a waterproof, 5-megapixel camera—so you can leave your old digital camera at home, too. The Exilim is covered by a protective coating so you can shoot underwater. It's also proven as being against shock. If you spend a lot of time at the beach, this phone will be your best friend.

　　Outdoors sportsmen should consider the unlocked Sonim XP3.20 Quest, which is the world's toughest phone--a claim I have tested. It can be tossed around violently, frozen, put into water, hit with a chisel, and used to hammer nails. Even if it does break, it comes with a no-questions-asked replacement promise.

　　The Nextel i580 is the way to go if you're worried about durability. Bear in mind: It isn't waterproof, it's water-resistant--it'll survive a quick dunk or splash, but you can't submerge it. In my tests, it survived freezing, washing, dropping from a second-story window, and getting run over by a sports car. The i580 also has great call quality and a built-in MP3 player.
