I have an iPhone 3GS and I know that Bluetooth is under settings and General, but I just got a car that can connect to my phone via Bluetooth. The downside to that is that if I do not turn off Bluetooth, all of my calls will go to my car, regardless on whether or not I am in my car.
It is hard for me to remember to turn off Bluetooth because it isn't staring me in the face, so I need to know if there is any way to get a "shortcut" to Bluetooth on my home screen so that I can remember to toggle it on/off.
