DEAL or NO DEAL? FreedomPop: BYOD: Unlimited Talk, Text, 2GB of Data Per Month Free ($20 Top-Up Req.)

ps: Unless what you mean is a Sprint CDMA iPhone 5 that also has GSM. That should work on FreedomPop.

Traditionally the CDMA carriers have been pickier about allowing a phone not made specifically for their network to work on their network. Whereas GSM phones, once unlocked, can work on any GSM network. (Given limits like 2G GSM going away, and supporting necessary frequency bands.)
