Upgrading with Sprint? How much did you pay?

[mamiamjo]

I have been thinking about upgrading my one year old Sprint Touch. I went to the Sprint store and they told me if I wanted to upgrade, it'd cost me about $500??
They said that since I only had the Touch (and new contract) for one year, I only qualify for a $75 savings off the full retail price of $579. That means I miss out on most of the instant savings and the rebate.

This seems ridiculous to me. I have been a Sprint customer for over 5 years and have gotten my wife, both of my parents and my SIL/BIL to sign up with Sprint, but Sprint is going to treat me worse than someone who never gave them any business at all.

So for those of you that have upgraded, how much did it cost?
