That's because phones and airplanes were operating on the same frequency. They don't do that anymore... in part because there's a dozen phones on every flight that haven't been put in airplane mode.

No they don't. GSM is all over the place with frequency, but it never goes down to 118-137 MHz which is where air traffic sits. It's just that mobile phones will increase transmission power to reach cell towers and that can produce that annoying disturbance. Phone won't mess up instruments, just annoy people trying to talk and get your ass safely from the ground.
