Samsung Electronics unveiled SPH-W7100 cell phone in Korea market. Targgeted for children and woman, this clamshell handset sports a built-in SOS function which could ring a loud alarm (up to 100db) in emergency situations. And if the owners get lost in the dark (just like those scene on horror movies), they can use the phone’s built-in LED lights to explore the dark. Or simply ask for help by sending their current position via text message, thanks to the integrated GPS receiver. Pretty much useful, isn’t it? Too bad it doesn’t come with ’stun gun’ feature…
