Bluetooth 4.0 became official recently, and now the first app to use this technology has made its way into the app store. The app, Find My Car Smart, is part of a Kickstarter project from FMC Smart. If funded, the company will make a Bluetooth 4.0 module that'll sit in your car. When you park, the module will trigger the iPhone app, which, in turn, will mark your location. This information will help you find your way back to your car, even in a crowded parking lot.
Bluetooth 4.0 is the latest version of the wireless technology to hit devices. It's meant for low-power, sensor-filled devices like the car dongle above. The specification was only recently finalized, and consumer products using it are expected to debut in 2012. Once these products hit the market, Apple owners will be ready and rearing to go as Bluetooth 4.0 is already supported by the iPhone 4S, the Mac mini and the MacBook Air.
