Indeed Sprint is CDMA although their newer towers could support GSM with a software update and they do own some 900 Mhz spectrum, I'd be surprised if they go GSM. I'd also be surprised if the Airave radio is software upgradable.

The only Sprint femtocells I know are Samsung Airave, and they are CDMA2000,
i.e. not related to GSM at all.

I have one of them here, just out of curiosity.  It seems to be a very
custom hardware design centered around Altera Hardcopy ASICs.

As Sprint is a CDMA operator (correct me if I'm wrong), it sounds a bit
strange for them to offer GSM femtocells like you claim.  Some quick
web searches turned out that the Airvana supports EV-DO, which once again
is a CDMA2000 feature.

I don't see how this fits at all with GSM
