You can customize your Sidekick by downloading themes at the following sites:

• Sidekick 3 themes
• Sidekick LX themes
• Sidekick Slide Themes
• Sidekick 2008 Themes
• Sidekick LX 2009 Themes
  
• Sidekick Themes for ALL models
  

Themes allow you to change the look and style of your sidekick 3 phone.

Normally a theme will allow you to change the background(s), the icons, the "bubbles" and hing sounds (sounds made when you open and close the phone).

There are a number of sites out there that allow you to upload themes you make or where you can download themes for free such as skthemer.com or sk3themes.com.

With the sk3 you can also change your keyguard (image displayed while locked) and your friend icons.
