i have only owned 2 sony phones the first was i think called T610 or something like that,the joystick gone faulty on that one & now i own the W850i which is the best phone i have owned so far,i have only had it for 2 weeks now so i hope it doesn't go faulty because i play games on it (i dont usually use mobiles for gaming),this phone is only let down by its very weak camera (really horrible) to take pics & movie clips. the nokia's on the other hand are solid quality phones i have owned about 6 of them & none have gone faulty,the software is basic but the phones have the worst design.i'm gonna stick with sony from now on.
