We’ve already told you that RadioShack is preparing to launch its MVNO relying on Cricket Wireless’ network. The launch date is apparently closer than we thought with the ad above suggesting that will happen on September 5th. Coincidently this is the same date when Nokia/Microsoft and Motorola/Verizon are having their own events and we’re not sure whether these are related in any way. I would say no, but you never really know. In any case, we’ll have all answers within two weeks or so. Stay tuned in the meantime, k?
