Google tried to bid on the 700mhz spectrum recently with added conditions to their bid.
google wanted the regulator to specify the winning bidder must give users freedom to connect any devices to the network, download any software, and the carrier must be prepared to sell of chunks of the spectrum to third parties wholesale.The Register
They got turned down. It is interesting though that google has tried this, as we can clearly deduct from this that the search giant is hunting for their own cellular network.
