OK stupid question time.
I've skimmed through pretty much all the entries on this thread and have seen some mentioning of requiring new devices in order to support Band 12 and maybe a few other bands, but lets say RRPP members and Sprint switch on LTE roaming today. I'm sure its dependent upon the LTE setup of each of the RRPP members, but what current devices, if any, would be able to take advantage of the roaming?
