Take a look at this. You can actually browse your FS in FAR now :). Just find your layout.xml and extract it.

Yesterday, I tried removing my operator logo by editing layout.xml, but that didn't work so well. I also have the w580i, and the layout.xml in my phone, was completely empty. No text inside, it was a 0kb file. I don't think you should mess with this if you don't know what you're doing, but if you're sure, do it =)

Happy Holidays :)
