It’s worth pointing out that even the author admits that the newer Stingray II has 3G/4G support. I think this is probably related to known insecurities in the AKA protocol, as researchers have recently found [1]. It looks like call interception isn’t so straight forward anymore, but IMSI capture and approximate location capture are alive and well. So unless you can verify that only Stingray I is deployed in the vicinity, I think it’s a stretch to say that the Stingray product “doesn’t care” about anything other than 2G.
