This app monitors the GSM/CDMA cellular network connection; displays a map of approximate cellular antenna locations and their RF signal strength; and can log the data to a text or KML file. *** Does not work on Verizon *** 3G & CDMA Support is limited by Android, not by the application *** CDMA requires Eclair ***Works best with 2G GSM. 3G/CDMA support is very limited.Please understand what this tool does and does not do before you rate it. If you are not interested in the esoteric details of how the cellular network works, please do not download this app, it will frustrate you and be a waste of your time. Please check website for details. I have reports that Verizon now blocks locations. Other providers may do same. Bummer. If your provider blocks, please be considerate and don’t downrate the app. Not my fault.Yes it is a battery hog – it needs to be.Froyo problems? Tested with HTC Desire 2.2, Galaxy S and Galaxy Tab.
