I am having a strange problem. The 3G connection is always on even after I close all the applications. I even removed the apps on the homescreen which require the internet. After I manually disconnect from Settings -> Connection mgr., again it evokes the connection. Pulled the BSNL 3G access point to lower priority and my WiFi point to higher. Now the WiFi connection is always on even though no app is open which requires the internet. What should I do in such a case.
