Excellent phone. Unique software architecture which is quite a departure from the style and format of Sprint PCS phones which was my previous carrier. My only issue is that the various menu interfaces are not as intuitive as sprint phone software menue interfaces. I have still much to learn and explore as far as phone functionality go but fortunately Cingular blesses you with a very detailed phone manual which Sprint was always negligent in providing such detail in their paperbound manuals. There are many charts and quick-guide cheat sheets in the manual which make for easy hunt and peck assistance with phone functions another quality lacking in Sprint.By the way, though my previous phone was blue tooth I had never used a headset with the device. It is truly wonderful to have both hands free and to even be a dozen feet away from your phone while making and answering calls. I love bluetooth, get a headset and put it to use, you wont regret it, especially if you like to be fully functional with your hands while having on the go conversations.
