No...I said that there were regulations regarding all sorts of electronics.
Specific targeting of cell phones is an FCC issue.
I had to avoid discussing FAA regulations for professional reasons

This has some extra information.
SDLucky7's link essentially agrees with my post(and links to relevant information)
BTW, there is strong evidence to suggest that cell phones(or more specifically cell-phone like devices) will never be allowed on planes. Not for a legal reason, but because it would be highly annoying. Why do I say this? Recent roll-outs of wireless internet aboard airplanes have all blocked voip services(this seems to be less of a bandwidth issue and more a fear of customer complaints). That is just my opinion though.
