Ok, Flame me for being stupid if you want, but I was just looking at the EVDO specs. Did you guys know there is a EVDO Rev.B? Is this the fabled WiMAX that sprint is working on?

The upgrade from EVDO rev A to EVDO rev B can be done with a software upgrade at the network. The software upgrade has been available commercially since early 2007.
TIA-856 Rev B

EV-DO Rev B is a multi-carrier evolution of the Rev A specification. It maintains the capabilities of EVDO Rev A, and provides the following enhancements:
  • Higher rates per carrier (up to 4.9 Mbit/s on the downlink per carrier). Typical deployments are expected to include 3 carriers for a peak rate of 14.7 Mbit/s
  • Higher rates by bundling multiple channels together enhance the user experience and enables new services such as high definition video streaming.
  • Uses statistical multiplexing across channels to further reduce latency, enhancing the experience for latency-sensitive services such as gaming, video telephony, remote console sessions and web browsing.
  • Increased talk-time and standby time
  • Hybrid frequency re-use which reduces the interference from the adjacent sectors and improves the rates that can be offered, especially to users at the edge of the cell.
  • Efficient support for services that have asymmetric download and upload requirements (i.e. different data rates required in each direction) such as file transfers, web browsing, and broadband multimedia content delivery.

Re: Rev.B

There's also a Rev C in the works. WiMax is a completely different (and competing) system and incompatible with EVDO. From what I've read, Rev C will not be backwards compatible. So no easy software upgrade.
