Dreamboard works differently than Winterboard, because it doesn’t require you to respring each time you switch themes, and it can achieve deep UI customizations without having to install other jailbreak applications…
This latest version of DreamBoard also includes support for lockscreens. We’ve previously reviewed DreamBoard, and we gave it positive reviews despite random crashes and some other minor issues.
I would recommend downloading this and checking out our iPhone themes center for reviews of many DreamBoard themes.
