Google Nexus One Field Test Mode

It is a bad news that Nexus One doesn't come with a decent default netmonitor function like iPhone or symbian phones. I don't have Nexus One with me. When I played my friend's one with code *#*#4636#*#* , it only shows you the cell serving cell id.

There is one application called "Netmonitor" in Android Market provides limited engineering mode. Here is the description from Android Market:
