Harald -

I agree with your comments in the strongest terms.  DO NOT DO THIS  
UNLESS YOU ARE ABSOLUTELY SURE OF ITS EFFECT ON THE LOCAL CELLULAR  
ENVIRONMENT.

Even if you do not directly interfere with the carrier's spectrum,  
you can still interfere with their service.  Remember that you are  
interacting with the cellular carrier, indirectly, every time you  
exchange phones with them.
