If you want to deck your phone out for Christmas this year, then try the Feel Xmas 3 Theme.
This free theme will inject some Christmas spirit into your Symbian handset, adding a festive wallpaper to the background of your home screen. The wallpaper features three white baubles dangling in front of of a sparkling red background. It's certainly very striking and utterly Christmassy.
Unfortunately, the rest of the changes in the Feel Xmas 3 Theme don't match up to the quality of the wallpaper. The new red icons are difficult to see properly in front of the red background, and any white text in the menus also becomes difficult to read because of the white in the background.
Feel Xmas 3 Theme is very festive, but it's let down by some poor design elements.
