Sony's Xperia Z is water-resistant, you say? We're putting it to the test. In this short video, Aaron attempts (and fails) to get it into a cup, so he opts for the more fun approach of semi-flooding the PhoneDog West office.

For T-Mobile customers that appreciate a phone that can keep up with active (and sometimes messy) lifestyles, the Xperia Z does a nice job.
