My car has Handsfree Bluetooth from the factory and when it connects to the iPhone, it pushes things like the ringer through the car speakers. Now when I'm in the car, I don't need my loud, long ringer going off. I had a Nokia 8800 back about 4-5 years ago which you could set a different ringer when it was connected to a Handsfree Bluetooth and it would switch to that profile automatically so you could just have a single "beep" or whatever as the ringer. Is there anything like this on Cydia or elsewhere that I can download? Thanks.
