Does anyone have any experience using an Audiovox SMT 5600 Smartphone sold by AT&T on a Cingular GSM network? Mine is working fine except I am unable to connect to data service via GPRS. That means no email or internet. Cingular customer service is clueless about the needed configuration of the phone. AT&T won't talk to me since I am not a subscriber and did not buy the phone from them (ebay purchase). I am able to connect to the GPRS services and get to the internet using my sim card in other phones so I am pretty sure it is a phone configuration issue.
Any help you can provide would be much appreciated.
