They also don't have 5gigahertz wireless.. only 2.4 they all know about 
bluetooth and all the phones have it but no one uses it. For wireless your 
phone will talk to your gps unit and your car will answer your phone while 
driving and the rest of the time they usually text eachother so it is not a 
big draw to use the bluetooth.
