A phone should initiate calls and receive calls. Period.
No need for a camera.
Or music player.
Or GPS.
Or video player.
Or photo viewer.
Or more that a couple of ring tones.
Or internet browsing.
Or wallpaper.
Or games.
Or tracking capability.
Last good phone made: Motorola Startac, which I'll keep using, even though Verizon keeps wanting me to downgrade to a current multifunction phone.
