What would Edgar Allan Poe be doing if he was alive today? That's right: clawing at the lid of his coffin.

Or perhaps not. Because, if a report from the Beeb is to be believed, an increasing number of morbid technophiles around the world are choosing to take their mobile phones with them into the next life.

Buried alive? Not to worry. Simply flip open your high-tech handset, fire off a quick text message to the undertaker, politely pointing out the situation, then lie back and wait for rescue.

Oh, and pray the battery isn't dead either.
