The HTC One SV (read our review) was released on Cricket only a few days ago, but a nearly identical model of the device has just passed through the FCC sporting Sprint radio frequencies. Although there are no images of the device to completely verify, the model number of this device -- PL80110 -- is eerily close to Cricket's PL80120. The specs that are decipherable from the filing lead to a little bit of confusion, however, as the physical dimensions seem slightly different from the current SV. There's also a few documents that list the device as a "Windows Phone," while the rest simply list "Smartphone." Bit of a head scratcher there, but typos do happen.
The radio frequencies being tested on this unnamed device seem to line up with what Sprint uses for its network, and no other carriers, so we can be pretty sure that whatever this device is it's heading to Sprint. We of course won't know for sure until we hear something official from HTC or Sprint.
