I am just learning about Bluetooth DUN. I have read through some posts on here to figure out the setup. I am using a Verizon Wireless Rizr (love it by the way). when I cannot to Verizon Wireless, I put in my username number@vzw3g.com and password, I read it was vzw, is this right? Tap OK, phone prompts to connect, select yes, phone says calling, then they 2 devices disconnect and the Nokia says "Authentication failed, try again?" What does this mean?
