iam not really sure about 5230 performance as i haven't had a chance to test it, but heard its good with some nice features.Sirjee, neither 5230XM will bring any seriousness. Strict advise is stay away from XM series, if not atleast from Nokia.
My experience with nokia os 60 phones has been way too good.maybe thats blocking me to see any negative aspects..
I've got 5700 and its pretty good with music and other apps. i think XM does have a edge over the normal phone with music.
