I just came from a D1 and I remember installing different gallery and dock apps from newer builds/milestone, etc...will these work with the x? If so can anyone link me to them? Thanks
Most of them just use standard launcher apps like Launcher2, LauncherPro or ADW and use custom images on them. All of them are available in the Marketplace.
Worst case you could install the apps and see if the developers have dock/launcher only images they could send you.
