Sprint Sprints new "legal" strategy to overcharge existing customers Internet

Somewhat like the Baggage Fees forced on the American public by the Airline Services, Sprint has now  imposed an additional $10 monthly charge on all smartphone users, as soon as they upgrade or buy a new phone. No matter if you have a Simply Everything, Unlimited or the highest paying plan, as soon as you replace your smartphone, beginning January 2011, you will now be paying at least $120 more per year, on top of your existing bill.
A very sneaky Sprint has figured out the way to get more from their existing smartphone customers who are stuck with a contract, some for 2 years! If you are eligible for that upgrade or simply need a new phone it is no longer a matter of just buying the phone, Sprint is charging every user who replaces their existing phone (regardless if already use a smart phone like a Blackberry) an additional $10 per month comes with it, supposedly for data usage (that you already were using on your old smartphone and definitely have been paying for).
Try fighting this one out, Supervisors will not even take your call once you ask the CSR to transfer you, obviously they too know they have no valid justification to do this- Sprint is simply IMPOSING this new rip-off on existing customers, particularly those stuck in a 2 year contract. You literally have NO choice, try putting any new phone, regardless where you got it from, on your plan to replace your old phone and you will be charged those extra $120 a year.
As far as I am concerned this is unacceptable as certainly was not part of my 2 year contract with Sprint, and I am only mid-way through,with a non-workable smartphone. I have no intention to pay $120 more for any or each phone on my plan. 
I think this calls for a class-action lawsuit: if consumers are expected to honor the 2 year agreement but Sprint can tackle on new charges for services we are already paying for (data plans) than we are being screwed, royally. What a rip-off, I have been a Nextel, then became unwittingly a Sprint customer, for years and would NEVER of renewed my contract knowing this. I want out of that contract, there are many other providers who will want my business.
