The first phone supporting all three of Sprint’s LTE bands has come through the FCC.

As Phone Scoop points out, an LG device bearing the model number LS-980 yesterday showed up, indicating support for Sprint’s current 1900 MHz LTE frequencies as well as the 800 MHz and 2.5 GHz the carrier plans to deploy in soon. The handset supports both CDMA and GSM.

The model number seems to suggest the device is an LG Optimus G Pro. That device is already available through AT&T and sports a 5.5-inch 1080 IPS display.

Sprint has already brought out a pair of Wi-Fi hotspots supported its tri-band LTE and it indicated tri-band LTE-enabled phones from Samsung and LG were in the pipeline for late 2013 release.

Sprint recently completed shutting down its Nextel network, freeing up some 800 MHz spectrum for LTE usage, and the carrier’s recently completed acquisition of Clearwire grants access to the 2.5 GHz band.
