8:45 AM -- There's a rumor going around that Sprint Corp. (NYSE: S) is working on a deal with Wal-Mart to put up WiMax towers at the supermarket giant's properties.

The Android Guys say they have a source that says that Sprint is working on a deal to place WiMax towers on the top of all Wal-Mart locations.

Just one problem with this that I can see: Sprint isn't deploying its own WiMax network; it is piggybacking on Clearwire LLC (Nasdaq: CLWR)'s mobile WiMax network for its "4G Now" service. (See Sprint's Summer of WiMax.)

So, assuming that there's anything to this rumor, just exactly which operator is talking to Wal-Mart and about what?
