LG VX-7000

I have owned the LG VX7000 since jan/05 and up until last week I never experienced any problems but recently my phone is either shutting off on its own or im getting dropped calls. Now I have noticed that the model is now discontinued do I either submit my phone to a verizon store and risk getting the same model or is it better to report the phone stolen and pay the $50 which I have insurance and hope for a new model or would they send me another LG VX7000?

thanks for your help
