Looks like Nokia had some plans (or at least patented something related) in 2007 [1]. According to ComputerWorld "The invention involves the use of radio frequency receivers in mobile phones, such as FM radio and GSM (Global System for Mobile Communications), to detect radio waves emitted by lightning."
Does lightning have any effect on the sensors that detect the geomagnetic field? Maybe even some small anomalies in the readings could be useful if many devices were working together.
