Summary: This is really very funky device3 by nokia. I like to keep collection of such rare things in my collection at which if people look, should wonder & ask "do nokia make production of such things also.....?". Compare to LD-3W it is very slim & sylish. The only thing is Non Removable battery. but each thing comes with som positive & negative side. So if you wish to buy the LD-4W then just simpaly buy it, dont thik too much & keep on comparing between LD-3W & Ld-4W.
