Here is a sample of 50 reports to NASA's Aviation Safety Reporting System that involve or could have involved PEDs. While many of the cases are just pax not turning off cell phones when told to, there are several that suggest strongly that PEDs did interfere with navigational equipment.

Of those that report navigation equipment anomalies, many seem to be related to the localizer (abbreviated as "loc" in the reports). Each localizer is associated with a runway, is used to assist landings, and transmits a highly directional beam on a frequency between 108.10 and 111.95 MHz. Cellphones transmit on frequencies around 850 MHz or 1800 MHz. It's hard to see how a cellphone could interfere with a localizer. On the other hand, FM broadcast radios receive signals in the 88-108 MHz range, and local oscillator leakage could conceivably interfere with localizers.
