does not support WMA.. all i know is that it supports MP3... you can download a software to convert Wma files into mp3
sony ericsson k800i format code
yes
The w580i has a very nice MP3 player, MF radio capabilities, web browsing, E-Mail, IM, pocket trainer, and a very nice camera. The internet stuff(web browsing, E-mail, etc.) aren't the fastest though, so not reccomended if that is what you want it for.
There could be two solutions to fix the problem.1) You have to re-install software / software update your phone.2) Its a cable (flexcable which is connecting screen to mainboard) inside the phone which is broken in some way, so you have to fix it yourself (don't do that) or go to the shop where its bought and get them to fix it through a repairshop!
