Amp'd's future looks to be as a content provider, not an MVNO.

"Its MVNO operation in the US appears to be struggling, but it's begun licensing its content platform to foreign carriers. Following a deal in August with Canada's Telus, Amp'd has now struck a deal with Japanese mobile operator KDDI that will make Amp'd content available to its 20 million or so subscribers. So is the future of Amp'd as a content aggregator and provider, rather than a standalone MVNO?"
