I SO CONFUSED!!! WHICH SHOULD I BUY???


I need to buy new phone. My old phone having some trouble. And it quite costly to repair. So it better for me to buy new phone. But I cant make a choice. emm...which one should I buy???? So confused but I need the phone...I dont care about the price but hoping not too expensive...
Joe, my dearest room-mate, had suggest to buy Sony Ericsson K770i. Is it the bright ideas??
