1. navigation icon.. is empty !... (I do have Garmin installed in storage card)
2. games icon also is empty! (also installed in storage card directory)
3. how to remove spb skins, after installed.. without removing the whole program..
You can add or remove icons by going to 'Spb mobile shell' (under the settings icon in programs by default) I think. Go to the advanced tab and then the 'menu' icon. Then select which menu item you want to edit (add, remove, move up etc). I haven't tried removing skins so I can't help you on that one.
