A BLUETOOTH phone headset frees up your hands — if you remember to bring it along. The LG Decoy may appeal to people who like to travel light, because the phone's designers have built a detachable Bluetooth headset into the back of the phone so the earpiece is there when you need to make a hands-free call. The headset is not the only feature tucked away on the LG Decoy. The keypad slides out from below when it's time to dial. Aside from its hidden hardware, the LG Decoy has plenty of other features, like mobile Web browsing and e-mail, a two-megapixel camera, a camcorder and the ability to play music and video (from the service provider). The headset has its own charging adapter, but the phone and earpiece can power up together on the phone's charger, so there is one less thing to forget to pack. – The New York Times __
