In my first post I had my cell phone on and connected along with other wireless devices ~2-4ft away with no hickups using 12 mini-standard servos running on my 6014 RX.
There is testing-abuse and ABUSE, placing a cell phone directly on top of the RX is ABUSE and will never occur when I am flying.
The cell phone I used is a Nokia 6010,2 wireless home phones, Linksys and Actiontec wireless routers and laptop wireless plugin adapters also built-in wireless.

I think placing any cell phone directly on any vendors RX, may - will cause problems.
The 14mz 2.4 TX module affected the phones as a blip of noise occurring quickly as it changed freq.

I have ~8+hours on my 2.4 module and it has been nothing but SWEET.
I am VERY HAPPY with my setup.
