Fines are not working at keeping people from using their cell phones while driving, should the penalty be jail time if caught using a cell phone while driving?

Would that finally get the message across to these people that using a cell phone is not only endangering their lives, but all the motorists around these people?
What is it going to take to get these people to stop texting, or talking, and start driving?
Is jail time the answer?
Maybe confiscation of the phone, and a ban on owning one for a set amount of time?
Why can’t people wait until they are done driving to make or receive a cell phone call or text?
