The popular skinning app for jailbroken iPhones, DreamBoard, is now free on Cydia. DreamBoard is a great alternative to Winterboard because it doesn't require you to restart your springboard every time you change themes. Dreamboard also allows much "deeper" themes and user-interface redesigns compared to Winterboard. Where Winterboard basically allows theme developers to re-skin existing iPhone graphics and interfaces, Dreamboard allows theme developers to build entirely new interfaces and methods of displaying information.
Apple has limited the number of home screens on the iPhone to 11. Even though that adds up to a total of 180 applications including the dock, some users want more space. This is possible on firmware version 3.1.2 thanks to a trick that doesn't require jailbreaking.
