Strange problem here. Each night I slide the switch on top of the Pre to silent so I am not waken by amazon emailing me at 3am. I then put the Pre on the touchstone. If I receive a call while the Pre is on the touchstone in this silent mode the Pre still rings. It isnt the normal ring tone and its not just as loud but it still wakes me up. There is no sound for emails or text messages just calls. Does anyone else have this problem?
