It's bluetooth function works pretty well for me. No additional software is needed to transfer pictures, ring tones with a Windows XP Pro. Worked with my logitech BT headset like a charm. Picture quality and the battery life are average.The biggest problem is the phone freezes from time to time. The first one I got freezed at least onece a day. Then I replaced it. the second one is better, but still freezes about once every week. Hope a new firmware can fix it.
