Right on the heels of last week's Clearwire Philadelphia launch, Comcast says they too have now launched their re-branded Mobile WiMax "High Speed 2 Go" service in the company's hometown of Philadelphia. Philly is Comcast's third launch market for the services, which have previously been launched in Atlanta and Portland. As is the case in all Comcast Mobile WiMax markets, they're actually offering some fairly decent pricing packages. The two flavors:

• Comcast High-Speed 2go Metro service costs $49.99 for twelve months ($72.95 thereafter) and comes with 12Mbps Comcast home broadband service and a Wi-Fi router. The service uses a Mobile WiMax data card that will obviously only work in areas where there's Comcast/Clearwire Mobile WiMax.

• Comcast High-Speed 2go Nationwide service costs $69.99 ($92.95 thereafter) and also comes with Comcast 12Mbps home broadband service and a home Wi-Fi router. The service uses a dual-mode data card that allows users to float between Clearwire's Mobile WiMax network and Sprint's 3G EVDO network.
