There are several versions of the following viral video going around where a few kernels of popcorn are popped using cell phones.

Not only is it impossible to pop popcorn with cell phones, they are most likely a viral advertising campaign seeing how many similar videos were posted the same day by a few users. It could be a massively coordinated joke, but be it a joke or viral advertising, they are fake. See Physicist Debunks Cellphone Popcorn Viral Videos, and Snope’s entry which mentions the popcorn bit while debunking an earlier version of the joke where somebody cooked an egg between two cellphones that were on for 60 minutes (also not possible). The Snope’s article also includes a video where the British show Brainiac expands on the egg experiment by using 100 cell phones.
EDIT: Turns out it was an ad for Bluetooth headsets.
