Jennifer at Cool BlackBerry Themes has created a very cool looking avatar theme available for the BlackBerry 9700, Tour, 8300/8800, bold, 8900, and the 8520. If you are a fan of the Avatar movie this theme will be a great addition.
A simple registration is all that is required (and well worth it) for the free themes on the site, not to mention the great selection of premium themes. Simply go HERE! and select your device on the left, select free themes and this Avatar Theme is under the Movie category.
