Query: DO NOT buy, and DON'T use Verizon

I can not tell you the frustration i have had so far with my krzr k1m phone from verizon!Firstly, I can't use the phone's capabilities, they are disabled.Second, there is seemingly no "back" button when using the menus, you have to start over!I have been a Verizon customer for years now and my trouble started when I upgraded to this new phone and I am very dissatisfied with everything, their service, the phone.former verizon fan,Nate
