 Any idea why?

The "secret" Phone Info screen shows signal strength (in ASU rather than dBm)
I've never seen a phone which can't get into that screen by dialling *#*#4636#*#*
some people tell me they can't, I'm not sure if they're doing something wrong though ... should be simple.
An Intent/Activity Launcher would be anther way to get into the screen via "com.android.phone.settings.RadioInfo"
