that the new iphone 4 has? I have had three new iphone 4's, and they all had problems with the bluetooth (bad connections) and proximity sensors! I really like the phone, but use my bluetooth alot, would be nice if they got it fixed! And the sensor thing too, so i wouldn't keep activating the screen with my cheek while on a call! Would like another iphone since i took all the others back! Just wondering about the 3gs? Afraid to try another 4!
