I’m not sure if this is new, because I didn’t know until @ASacco pointed it out, but the MyBlackBerry site has some free holiday themed wallpapers that you can install. Some of them are really well done and it’s always nice to have something official. I think it would be good to start including themes rather than wallpapers. RIM has the resources to be able to offer us all free holiday themes.
On that note, what do you guys think of MyBlackBerry?
