After launching the Xperia Play in September, AT&T is back with the Sony Xperia Ion, one of the first Xperia devices to drop the Ericsson name. If you can look past the fact that it's launching on Android 2.3, you'll notice that this is one of the most muscular phones ever to hit the market thanks to a 4.6-inch 720p display, a 12-megapixel Exmor R primary camera that's advertised to go from standby to ready in 1.5 seconds, NFC, and LTE — a first for Sony's line. It comes housed in an aluminum shell that's advertised as "thin, lightweight, and durable" and the screen is one of Sony's so-called Mobile Bravia Reality Display components — a technology that debuted on the Xperia Arc last year and offers a laminated, gapless appearance akin to the iPhone 4. Look for it to launch on AT&T this spring, and don't worry — an Android 4.0 upgrade is already in the works.
