Hi, I am using an unlocked blackberry bold 9000 which was bought in the US from AT&T. When I inserted my Airtel SIM in it and the settings have been done automatically. I changed the TCP settings(Settings->Options->Advanced Options->TCP). I assigned APN as "airtelgprs.com and left username and password fields blank. I then saved and came out of settings. And when I open browser then it shows a pop up msg saying:"Unable to connect to the Internet, please try again later. If problem persists please contact your service provider." The 3G symbol is being shown but I am unable to open any website. Anyone please throw some light on this....Regards,Pranay
