My wife have an iphone and data plan from ATT. I have a BB S2 unlocked, so I took the SIM from her I phone and inserted it in the S2. After reboot it pickup ATT service with EDGE network and all, but when I try to go to internet using browser it said "this is a wi-fi service, please ensure your device has an active wi-fi connection and try again". Please help me to get the browser working with ATT EDGE service, thanks.
