Pantech PN-210 / PN-205
Decent phone
Has 4, not one, programmable function keys
Has no camera, so is allowed most places I work.
Has only 2 external buttons to cause trouble.
Sound quality is better incoming & outgoing.
Has better performance in weak signal areas. Rural TX has plenty of low to no signal areas for me to appreciate weak signal performance.
It does lack EVDO modem & may lack USB connection capability.
