reason why i recommended w300i is that it comes wid hpm70 headset which allows u to plug in any headset according to ur taste and wallet!
(the bundled fontopia headset is better than any stock headset bundled wid any phone anyways) and a larger memory card out of the box!
wid 6233 u'll hafta buy a larger memory card (obviously if u r buying a music phone u wudn't wanna live wid a measly memory card!) and also the audio adapter which increases the cost.. definitely not ~10K!
