Is there a free app out there that can monitor BOTH 3G & 4G data usage for my Verizon LG Revolution? Most of the ones I have come across seem to be able to do it only for 3G (Watchdog, Traffic Statistics, etc.). I have '3G Watchdog' installed, but it doesn't seem to monitor my 4G LTE connection. I am in an area that is heavily covered by 4G LTE (Atlanta) so would like to accurately be able to keep track of it all. Any recommendations?
