As an owner of the current Airvana and previously owned Airrave, I was wondering if Sprint has any plans to come out with a 4G LTE version of these devices? Not that it's a killer if they don't, but just keeping my options open if I move to an area that has limited Sprint service. If they don't, I'll haul these with me. Then again, I probably would have to have an ISP giving me more than 6mb of DSL service just to keep up with the 4G capabilities.
