Man, Nokia 7210 supernova is the phone you should get.
i have it, sweet audio quality but for that you will have to buy a decent enough headphones n a 2.5 to 3.5mm converter(available for rs 20).
its available for 5.3k, it doesnt come with memory card so add 400 for 4 gb card + 700 for decent headphone + 20-30 rs for converter n you are ready to rock.
If you want to spend more than you have got only one choice , Nokia 5220 XpressMusic, available for 7k + 700 for headphone
