I use Verizon EVDO and have excellent service in DC for streaming cd quality from Launchcast and streaming live tv from my Orb server at home. Of course if I am travelling outside of the area the performance drops.
I did have major issues using a PC5740 card...dropped connections and seems like the content got filtered a lot...even without using their vzaccess software.
I switched to the USB 720 by sierra and now its excellent.
I await the mod...please put me down as a beta tester!!!
