A new phone bill charge called "Oops"

This is soooo true! We actually discussed this in my accounting class this afternoon! A firm that overcharges its millions of customers by a mere nickle per month will, over time, end up with tons of money they were never meant to have in the first place!

And while we're on the topic of cell phone bills...
Why do people buy fancy cell phones? Why should we be paying for service and then paying for the very instrument we use so they can charge us?
Can someone please explain this, I've been wondering about this for a while.
