BluetoothIt takes four actions to enable Bluetooth on the new iPhone.

  1. Click “Settings”.
  2. Click “General”.
  3. Click “Bluetooth”.
  4. Click on/off slider.

Leaving Bluetooth enabled all the time drains the battery much too quickly, so it makes sense to only enable it when you are using it, and to disable it when you are finished. (The same could be said of 3G network access.) Hopefully in the next release of the software they’ll make it easier to flip these two settings. I mean, I know it’s not world hunger or anything, but four clicks is at least two too many.
