I was just wondering if the iPhone could produce the 315 MHz frequency like a "fob" to allow keyless entry to your car???....... Sounds pretty cool.......I looked into the technology and Im pretty sure the iPhone doesnt have all the key components.......... If anyone can think of some other way like maybe a Bluetooth linked conncection with the computer in the car???..... Just some backburner thoughts...... Feel free to correct me anywhere or just put in some general input
