anyone seen an app that simply reports yours signal strength? the built in one (settings > about phone > status) seems to report, but in a way that makes some sense. for example, anyone know what -90 dBm 0 asu really means? I have a cool app called GPS test that shows the GPS strength - bar chart and number and color - of GPS signals. I would love something like that. anyone seen one. I have another app called No Signal Alert that tells you when you have lost your signal. I emailed them to incorporate a signal strength meter, as it seems a logical app to have it.
