The Sample Skin got another Update, just now. It now offers you even more possibilities:

• more colors (tab font, fonts in toaster, contacts,…)
• more Images are applied
• moving/resizing the close, minimize and maximize/restore buttons
• full phone xtra control
• move/resize the toaster windows
• changing main font style
• using background images for the contact list
• modifying the corner radius of the main window 
• compatible with all versions since Build 5352 (just some text colors won’t be applied in Build 5352 and 5354)

You can download it in the forums’ ICQ section in the Skinning tutorial.

Have a lot of fun with this.
