LG's security phone

Responding a recent spate of kidnappings there, manufacturer LG is selling a phone with extra features designed specifically for dealing with emergency situations. At the press of a button the "Aladdin" will display the location of three different subscribers (so you can get help) or automatically send a photo to three other people.
And SK Telecom has a new service that periodically sends text messages to family or friends with information about your location, so if you disappear they can immediately know your last reported location.
