Help for w810i

Hi everybody,
I have a SE w810i, CID 49 , Software version : CXC 1250316 R4EA031
can i change the skin of walkman and installing patches ??
if it is possible, tell me how
Thanks a lot :)

Yes,you can and use this tutorial How to apply patches with Se Tool 2 Lite on DB2010 phones - Top Sony Forums and you need to use XS++3.1 Darwin for uploading Walkman skin to phone

Can you just copy files to the phone in a specific folder for themes and skins?
