Steps to setup 3G Modem

Hello,

I am having trouble getting my 3G USB modem working on PFSense 2.0 on a ALIX 6F2. I would like the 3G modem to work as the WAN, allowing the LAN to connect to the internet thru my 3G service. I am using a supported 3G modem (ATT), its a vodafone E220. http://doc.pfsense.org/index.php/Known_Working_3G-4G_Modems

I followed the 3G configuration tutorial http://doc.pfsense.org/index.php/Configuring_3G_modems
When I connect, it shows the interface is up, but I cant browse the web thru the LAN.

Other things I tried:
I added OPT1 to the System>Routing list, making it default.
I added firewall rules to open all ports on OPT1.
One strange thing is that when I select ATT, it uses a username of ISP@CINGULARGPRS.COM. Is that right?

Is there a step I'm missing?
Do I need to add OPT1 to routing list and setup firewall rules for 3G modem interfaces?

Thanks!

Here are my logs after connecting OPT1.
