I have Sprint, and understand they charge for call forwarding. So, to my understanding, even if I use any third party software such as Call Director, or Plug Forward, I would still be charged the call forwarding fees? Is there any third party software which allows you to forward calls with Sprint and avoid the fees?

If not, has enyone been successful in getting, say free call forwarding as a retention, or an addon to their plan? Is that something that a Sprint CSR can do?
