T-Mobile had more than just big updates at its CES event; it gave us opportunities to try both its newly national HD Voice service and a seemingly unknown carrier-specific NFC app, Tap Tag. The currently Android-only software is best described as a crossover between somewhat simpler existing NFC tag systems. like Samsung's Tectiles, and multi-step automation like Motorola's Smart Actions. Put a Tap Tag-equipped phone against a relevant marker and it will perform one or more customizable tasks, such as putting the phone in a do-not-disturb mode at the same time it sets an alarm for the morning. From our glance through the menus, it's surprisingly deep and flexible without being intimidating. There are pre-defined templates, but nothing's set in stone -- if your definition of an office mode involves launching YouTube and cranking the volume, you can make it happen.
More details, including HD Voice testing, await after the break.
