You would think that in a time when almost everything is customizable, and the Sidekick target market are artists and other creatives, Danger (the makers of the Sidekick) would allow you to play away. Well that is not use case, until now. There is not a Zipped file floating around the web that allows you to create and manage custom backgrounds and themes for your device.
How to? Well all you need to do is find the file here, modify a text file, drop a few images via USB, and now your SK3 feels like it is yours. You better do this quick because it can be locked up at any point.
