I wana buy Nokia5800 3G 16GB express music mobile phone. I've read a review, but hardly find any demerit. if anyone has personal experienced, let me know why sud I buy it? or why sud not I buy it?What is the demerit of Nokia5800 3G mobile phone?the 5800 is only 16gb if you put that size memory card in it. the only 'bad' point of the phone is the 3 megapixel camera. the blue vodafone model is the one to go for, you won't be disappointed.
