After months of speculation, rumors, leaked photos, and even a pricey teaser ad that aired during the Super Bowl, Sony Ericsson finally revealed details about the Xperia Play, a device popularly referred to as the “PlayStation phone.” Sony Ericsson unveiled several new phones this week at the Mobile World Congress in Barcelona, but it’s arguably the Xperia Play that is getting the most attention. Last week’s high-profile TV commercial confirmed the device’s existence, but this week is about seeing what it can actually do.
