In addition to free Sidekick 3 themes, T-Mobile has finally included themes in the Download Catalog. This means that you can download a theme direct to your device if you’re willing to shell out $1.99 for the convenience. This also lets Sidekick iD owners customize their devices finally. Sidekick iDs don’t have a memory card, so you can’t load your own custom themes and backgrounds on them like you can with the Sidekick 3. To download themes direct from T-Mobile, check out the Download Catalog. For more information on creating your own custom themes, check out sk3themes.com.
Thanks to Fully for the screenshots
