Analog  TV phone let you recieve old school anlog TV signals, and are very handy for areas that have not upgraded to DVB-T yet.  Having a TV mobile phone on you means you'll not be missing out on all the free TV just because you aren't at home. 

Please note that that analog TV and digital TV are different and  digital TV standards are different in different parts fo the world.  So be sure you check up on your local digital TV standards before buying the wrong phone and then telling us that your phone is broken (yes, this really happens).
