iPhone 4 spontaneously combusts

It was your pretty standard Regional Express flight from Lismore to Sydney...well up until a passenger's mobile phone self-combusted shortly after landing.

Luckily the phone wasn't in the passenger's trouser pocket at the time, and no people on board were harmed.  After the plane landed, the iPhone started to glow red and emit a dense cloud of smoke, which the Flight Attendant was quick to extinguish.
