Keep track of when and for how long your phone loses and regains network connection throughout the day. Run this app and leave it running in the background (push the 'home' menu button of your phone instead of the 'back' button.) It will monitor the state of your phone's network connectivity. If you loose internet (3g or wifi), the app will save a record of the event. Push the 'back' button and you will be given the option to shut down the monitor.
