While at CTIA 2013 I had the opportunity to attend a media event where I ran into the folks with Bullitt Mobile who via a partnership with Cat, the heavy Equipment people just recently announced an exciting new rugged Android phone called the B15.

According to all things Digital:

Caterpillar is best known for making heavy equipment, but the machinery brand thinks it can add something to the phone business.

Cat has partnered with Bullitt Mobile, a British electronics firm that builds products using well-known brands to develop a rugged, waterproof Android phone.
The easiest way to make phones rugged is to just wrap them in a ton of rubber. But that also makes them big and bulky — something Floyd said his group was looking to avoid.
“It’s got to be a great phone — something that everybody would feel comfortable carrying,” said Dave Floyd, director of technology for Bullitt.
The result of their work is the Cat B15, a phone that is debuting at the CTIA trade show in Las Vegas and will sell for $349 without subsidies. The device packs a 4-inch screen, a dual-core MediaTek processor and the Jelly Bean version of Android into a device capable of surviving a 6 foot drop onto concrete and withstanding up to 30 minutes in 3 feet of water.
Its screen is also designed to work with a wet finger — something that trips up most smartphones. And all that in a phone that weighs just under six ounces.
Bullitt isn’t talking carriers yet, but it’s a GSM phone with support for HSPA+ networks, so either AT&T or T-Mobile USA would be a good fit.
