Folks! I got my new HTC Tattoo few days back. But I am having problems browsing the net using Wifi. When connected, I can browse for just a couple of minutes. And then the browser does not respond. Sometimes, even when connected to Wifi, the browser does not respond. But i can access other google apps. Also, i can't surf the net using GPRS. I have done the settings for Vodafone(India) but how do i connect to GPRS/EDGE? Any help would be appreciated. Thanks!
