hi ive had 5 d600s all on contract all had problems 2 screen faults 1 the video to tv output not working and 2 kept freezing up after 2 or 3 weeks of use had my w800i for 3 months now no problems amazing phone i was always a samsung fan and motorola just for the menus but w800i is definetly a home run for me.
also a e1 rokr is just as good as a w800i just cheaper and no radio or infrared
