Verizon EVDO Issues

Update...

First, thank you to all who replied off list. The general summary of the 
offlist replies, is that a PRL update may be needed. This of course 
doesn't appear doable via Linux, and our vendor (IRG) swore up and down 
this wouldn't be required.

We had the tech remove the USB dongle (model 720) from the system and 
place it in his laptop. Came up and worked fine once vzaccess twiddled 
whatever bits it needed to.
