^^ 5130 is an awesome set in 9200Rs. N70 is out of date & very old set, its features are also of very very old version, its just popular because of the Symbian Application, thats it.
If u dont want Symbian Application, go for NOKIA5130, its a cheap music set with lots of up to date features, and its price i.e 9200rs for new set is very very reasonable.
