Ok, changin your front display is really easy. You first need a cl.gif image, this site has a few, and you can find lots of sites that have them, here is a great site that has them and has links to great wallpaper sites too here is the linksy..
Media page - Hack the V3 . As you can see, the CL.Gif images are right there. Then you need P2KCommandor, it's free if you look. And you just install the drivers, and look in System and you will see a CL.Gif image, yo ujust delete that one, and put this one in place, and bang, new front display.
As far as dust and stuff goes, I use a very soft cloth, check out your local office supplier, like OfficeMax. You want to find the brand called Fellowes, they make
LCD wipes, soft cloths, compressed air, and all of them are very good.
