The Optimus Chat is an entry-level, touch-screen smartphone with keyboard manufactured by LG Electronics, Inc. While it is very similar to the LG Optimus One, the main difference is that it includes a smaller touch screen (2.8-inch instead of 3.2-inch) but has a slide-out keyboard instead. It is currently running the Android 2.2 Froyo software stack but may run Android 2.3 Gingerbread.
