I've noticed that a lot of people here have been having this problem. To fix this, SSH into your phone and do the following:

navigate to /private/var/mobile/Library/Customize2/Cache

delete all of the files that say ThemeListByChar0 thru ThemeListByCharZ

Now when you go back into Customize2 and browse themes, it'll re-check the online directory for themes rather than checking the cached file.

Don't forget to hit "thanks"

Sweet fix, thanks! I've been wondering how to fix this.
