i was gonna suggest u the W810i, but u seem to be inclined to the 3G/A2DP. which i believe even if it cums to india will be expensive. as broadband in india is pathetic, i knw both r diff stuffs.
anyway, w810i is a brilliant phone. it has the best cam among 2mp, same as k750i. n the walkman player is awesome. even its nterface is cool n intuitive, no cybershot phone can compete with it, excludes k850i though.
well, k800i jus seems to fit ur bill. its cool, sturdy, has a better cam. but i'd suggest the k810i, a bit advanced bro of the former, n luks gud too. he k800i's cam cover is irritating, it opens ven u dnt want to, in ur pocket. n k810 is slimmer.
n regarding a2dp, its comparatively expensive, n ppl hardly use it. we get fedup chargin our mobiles, now who'd go mad after chargin the headphones too, or replacin batteries n stuff.
anywayz, to each his own.
