Is Myxer.com a scam? Or does it really give away free ringtones? (Read Detail)?

And please dont suggest myventones.com, it doesn't support boost mobile.
I have a Boost Mobile phone. And the plan i have has free text messaging, free internet, and unlimited calls (also free). So does myxer.com really work??? Any recommendations on other sites i should use??
