Possibly.  Totally depends on the strengths of the signals.  Close to high 
power transmitters, yes.  But that means broadcast transmitters like TV and FM. 
 If you have a 100 watt cell phone transmitter right outside your window, you 
might be able to do it but I would not want to live there.  

Being near anything broadcasting 25 kW or more it would be easy.  NEAR is the 
important word.

With the amount of RF always traveling through the air, in an average urban 
environment if a guy has some magic antenna to stick up and capture everything 
flowing through tha point in space, could you steal that energy and charge a 
cellphone?

you are reassembling were disassembled by you. Therefore, if you can't get them 
together again, there must be a reason. By all means, do not use a hammer. --
