This is what we like to see. Comcast is entering the 3G/4G wireless network market, likely becoming an MVNO on Sprint’s wireless 3G/WiMAX 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.
Seeing as the US has got a semi-consumer friendly administration in office, the FCC will likely make sure that Comcast doesn’t throw the kill switch on other VoIP providers like Skype and Vonage. As this kind of service becomes more popular, Computer companies like Apple will start throwing 4G radios into their iPods and iPhones.
