I can't connect (I can't even see it) to my bluetooth keyboard on my 3G on OS 4.0, in fact I can't even get my iPhone to connect to my mac via bluetooth anymore. Do you think its just a bug, or do you think Bluetooth keyboards won't be supported on the 3G? Or maybe my Bluetooth radio is broken, has anyone else been able to get it to work? I really want to use my iPhone to take notes in class.
