Cool! Not terribly informative to somebody who doesn't know what it all means. Somebody should build an iPhone app to capture all this information along with GPS coordinates, and let you build signal maps and so forth.


One of the EricaUtils will grab your current coordinates. I bet CoreTelephony has a signal strength variable. Hm.
