i believe so because when i messed up the firmware of my K750, i would occasionally get a flashing white screen whenever the the walkman player hit a song...it was specifically a FS problem so maybe reflash your FS

im also curious, what area do you live in where you can get a w810 on pay as you go? also how much did you pay for it because if its cheap id buy one too, here in Canada w810 is contract phone from rogers
