The NEC 515 is a phone used with the former AT&T ("Cingular Blue"). While it is slightly older than many of the currently "hot" phones, it has some clear advantages. First, it is a quad-band GSM, meaning you it will work just about anywhere in the world. Second, it is easy to unlock; for about $10 and about 10 minutes of your time, any bozo can unlock this phone to make it truly world-capable. It also has a very large, very sharp display, which is great if you're sick of the crappy LCD's that manufacturers have gotten accustomed to using in their phones. It also has a dedicated co-processor for games, and uses the DoJa standard for mobile gaming. Games run fast and look great on the high-quality display.
