You probably want to keep it looking new and who can blame you. It's like a new car, and you're dreading your first ding or scratch. I know, I've been there and I'm a perpetual phone dropper!
Regular readers of my columns know that I use a lot of different cases, depending on the occasion. For formal events, I might put my iPhone in a slim case and slip it in my suitcoat. But for travel, I use an OtterBox and have done so since the days of my first generation iPhone.
On a recent cruise to the Caribbean, I used an OtterBox Defender for my iPhone 3G. It's not quite waterproof, but plenty rugged. OtterBox used to make a waterproof model for the original iPhone, but few folks were willing to risk swimming with it! The Defender provides the coverage most folks need and now it comes in a variety of colors besides basic black, including white, yellow, and pink, with and without black accents. I think the white with black accents model looks like standard issue for a Star Wars Stormtrooper!

OtterBox even has a contest where you upload a photo showing your OtterBox in some unique location and you can win prizes! Check out my photos and those of others at http://www.PlanetOtterBox.com!
Enjoy your new iPhone and keep it protected!
