They are used for external antenna's.

In the old days before bluetooth car kits, the phone would sit in a carkit cradle, with a little plug that goes into that connector. The cellphone signal would thus be carried outside of the car, making it "safer" to be in the car.

Now days, certain poeple have use for them - but alot of manufacturers are leaving them off.

Some people in remote locations can also fit a directional antenna and can then have better reception.
