uuuuummmmmmmmm no

Umm let me see...
 

Are you CRAZY homebread do you know how many people would kick your bot if you did that.

Most cell phones in the US operate on the 1900 mhz band, and the international ones operate on 1800 and 800. None of them interfere with the radio modems.

I think it was mentioned before, but FIRST will catch you if you try this. Not only do they scan for the radio signals but there's a set of LEDS that indicate any problems between the robot and the radio link
