I bought a Timeport 270c on Ebay for my Verizon account. the phone was originally used on an Alltel network. after registering the ESN with Verizon the reception was spotty and it kept dropping calls. Verizon said the software needed to be updated from the Alltel version but they were unable to do it for me.
Motorola says it can't be done from one carrier to another.

I don't believe them!! anyone had any luck flashing the memory?
