Ed,

Thanks for the info.

 I replaced my LG VX4400 with a VX4600 in November, 2004.  IMHO, the
 VX4600 is a better phone the the VX4400.  It holds the digital signal
 better and has a longer battery life.  The VX4600 has a smaller size,
 high resolution and larger screen, clear and loud audio, and stub
 antenna.  Both phones have the same intuitive menus. On the other hand,
 the VX4600 is all digital which is not a problem for me but might be a
 problem for people who need analog service.  VZW no longer offers the
 VX4600 on their webiste so you will need to shop elsewhere.
