Which is ur mobile phone??

sony ericcson w810i

i have got a nokia 6233 its quite new i got it free with a contract its a nice phone and has 3d audio unlike a lot of older mobiles that only have one speaker and when its playing loud on a single speaker it sounds awful mine sounds good with 2 speakers on it i have the black fronted model and not the other silver one, the only bad thing about it is when i pull it out of my back pocket the battery cover sometimes comes off it.
