Confused about this Freedompop phone from BestBuy

Saw this FreedomPop phone on Bestbuy. Says it's Freedompop in the title, but says "internal carrier - not applicable". Says it has cdma as well as gsm, so can it be used on any carrier, including non-Freedompop?

Maybe it's Sprint CDMA with 3g gsm capabilities? And maybe the gsm part isn't compatible with u.s carriers? Dunno.

Looks like 180 days of service is the new norm to unlock prepaid phones.
