I have the official iphone bluetooth headset (a1221) and an iphone 3gs with 4.0.1, and it does not function as it used to. I used to be able to see it's battery life on the phone and it would automatically pair when I plug it in. Why hasn't Apple put this functionality back into 4.0? It was one of the best features of the headset. I know it is not as big as it used to be, but you think an official iphone accessory would be very easy to use with an iphone. Agree with me? Complain to Apple.
