Hold down the ALT key on your BlackBerry and type the letters NMLL in the same sequence -- the bar graph indicating signal strength will convert into real numbers indicating the exact strength in dBm.

From my day of testing, I've determined that the iPhone 4 performs much better than the 3GS in situations where signal is very low, at -113 dBm (1 bar).

I can honestly say that I've never held onto so many calls and data simultaneously on 1 bar at -113 dBm as I have with the iPhone 4, so it's readily apparent that the new baseband hardware is much more sensitive compared to what was in the 3GS.

For the ground, which is fairly non-fluctuating, 13 dB SNR provides a 90% probability of detection with a 1e-6 probability of a false alarm i.e., spurious, which would require 53 dB of gain for a -154 dBm signal.

To get good throughput you need to have an RSSI in the -70s dBm.
