LG VX-9400

Which channels can the tv on this phone access? Anything cable like MTV? Is there an extra cost for accessing the tv? Also, I thought that I remembered seeing a GPS system on this phone. If so, is that included with the phone, or do you need an extra subscription with an extra cost? Lastly, does anyone know whether or not this phone can be unlocked and used with a different carrier such as T-Mobile? Thanks...
