My husband and I purchased these phones because we wanted MP3 players on our phones and liked the design. The phone has had problems and just shuts off completely at any time. It doesn't just hibernate it actually turns off so you don't realize that it is off and miss calls. My husband has called Cingular and they will just keep sending the same phone. He has had three and they all have done this. Mine has not started doing it until recently and I have had it a year and a half. There are other phones out there (perhaps some of Sony's newer versions of this series) that are better. The interface is nice and you can activate the music portion w/o the phone being on.
