I use a prepaid cell phone for almost all of my phone needs.
I carry it while I'm out of the house, but I do not answer it while driving, nor do I ever make calls while driving. To me, a telephone is a convenient tool, and like any tool it is my choice whether or not to use it. If use of a tool endangers myself or others, then it is my responsibility to avoid so endangering people.
Personally, I do not think that there is any need for any specific laws regarding cell phone use while driving. We already have available sufficient criminal code - just use it. Charge any person involved in an accident while using a cell phone with felony reckless endangerment, along with negligent operation of a motor vehicle. Showing that they were using the phone at the time is pretty simple - cell phone company usage records track times of calls and also track cell tower signal hand-offs - the info is there to be obtained by subpoena. Simply make such a subpoena a routine part of processing any injury accident, make getting cell phone numbers from motorists involved in accidents a routine part of investigation.
