Can you use a GSM Triband phone with Sprint?

I'm not sure, but the Sprint networks are CDMA as opposed to GSM.
I was wondering if you could still use it because of the frequency.

not HT but no you can't you can only use sprint phones (even if your phone was triband CDMA if its not a sprint phone you can't use it)
