I want to have them on SD Card. Is it possible? Do we have any free application which will monitor the Internet Usage i.e. Mobile Internet (Vodafone India). Currently m using 3GWatchDog. Do we have any free application for monitor the call, SMS etc? How to toggle between 2G and 3G network very fast. Do we have any widget for this? How can we expand mobile's battery life? I don't want to make SYNC google mails but want to use g-talk. But whenever connected to Internet, google mails are automatically try to get sync. How can I disable mails? Do we have any video player which supports all formats like flv,mkv etc? If we uninstall any application, do we having any tmp files in phone memory. How can we delete those?
