I got an email from someone who wishes to remain anonymous who saw either my previous blog posts or my TabletPCBuzz.com posts about my EVDO woes.

He suggested tunning off some Bluetooth ports and trying again.  Sure enough he was right, it does appear to be a COMM port issue.  Best of all, now the EVDO is working on the Toshiba Tecra M4 that I have with the 5220 card.

Meanwhile, I have gotten two cards sent to me by Verizon to try out because we were pretty sure in our troubleshooting testing that it was the 5220 causing the problems.  The new cards are suppose to be the: KPC650 and the PC5740.
