you want to say that i need to use acoustic compatible with w880, w660 or w850? am i correct? and do i need to flash my firmware as well or just patch them with setool2lite? which way is faster? xs++ or setool2lite? i don't prefer far manager as it looks quite complicated. and one more thing - if you answer my last question then maybe you could provide with the link to the tutorial as it gets really confusing in here and i really don't want to mess my phone:) thanks very much
