This is what we like to see. Comcast is entering the 3G/4G wireless network market, likely becoming an MVNO on Sprint's wireless network (anyone else have 4G?). They are offering a combination package for $50/month in select metro areas. What's REALLY interesting here is that Comcast also has its Digital Voice service which works over VoIP. It isn't a stretch to think that they'll soon be offering their voice services as a wireless product, unless Sprint has something to say about that.
