More and more people are living the high-tech lifestyle. And as gadgets get cheaper, more people have them, and lose them.
In a British survey, in London alone more than 63,000 cell phones have been left in the back of cabs in the past six months; that's about three phones per cab.
Over the same timeframe, almost 5,000 laptops and 5,800 PDAs such as Palms and smartphones were left as well.
Jemima Khan reportedly left her iPod, phone and purse in a cab and asked for them to be returned to her friend who turned out to be Hugh Grant.
With Briton's growing love of phones, the Mobile Equipment National Database was created to allow people to register the unique ID number of their phone so it can be returned in the event it was lost or stolen.
Hugely successful, millions of gadgets are registered, and organizations such as Transport For London regularly consult it when trying to re-unite folk with their devices.
For the cab drivers, finding a phone in the back is one of the more pleasant things many have found. The survey of what else has been left behind included a harp, a dog, a hamster and a baby.
