Problem using GPRS on ADH8066

Hello, I have an ADH8066 which is working fine so far. My issue is pulling a web page using GPRS. I have done the following:

AT+AIPDCONT=“internet” // edited as necessary with the correct APN, username, and password

AT+AIPA=1 // at this command I as assigned a private IP in the 10...* range

My provider gives me two other settings, but I’m not sure where to put them:

WAP IP 1 172.016.007.012

Wap Port 1 9201

At first I thought it was a proxy, so I attempted to pull a web page how you would do it using a HTTP proxy server. That gave a 304 socket error. So I tried to pull a webpage directly. Same 304 error.

Any ideas on how to use that IP address and port?
