New phone will scream if it’s stolen

LONDON - Now if your mobile telephone is stolen, you can scream — and your phone can, too. A new service launched Monday is designed to deter mobile phone theft by equipping telephones with an ear-piercing scream.

The screaming won’t stop unless the battery is removed. Even if the thief replaces the phone’s SIM card, the handset will not work.
