Like Brother said, the current generation of cell phones nomally should not cause any problems. Their filters and transmitters are much better than the earlier generation.

I usually sit in the cockpit and realize that my cell phone is still on sometime around 30 minutes after takeoff and we are level at 39,000. Considering that the phone is 2 feet from the instruments and not 100 in the rear like the pax, any issue would have show up and fast.

I have worked for McDonnell Douglas, Boeing and Bombardier. Everyone of these companies builds airplanes for the military and during the testing they bombard the planes with loads and loads of radio wave and radar radiation to simulate their being in combat. No problems with them at this time so doubt that one or two cell phones or blackberry is going to cause any problems.

Course you need to realize that this is all about money, (not safety) and its the money that the airlines get from the in-flight telephone calls. When they figure a way to make money off of cell phones then it will become legal...
