Worked wonderfully.  100% solid signal obtained consistently by Celltrack on a Nokia N8.  The differences when the amplifier was operating and not were quite dramatic indeed both, by the numbers and in actual call clarity and data rates.  Testing data speeds with the amplifier on, I was consistently reaching 3.5+Mbps down, 512+kbps up in a local rural area that tends to be problematic.  The internal Wilson antenna can be placed behind the phone itself in 3rd party cradle or mounted as instructed, both working quite well.  The external antenna base has a strong magnet that will properly affix to the car roof unlike some lesser magnetic antennas.
