Along with the H10, I noticed that, lo and behold, it uses the same screen size as the iAudio X5, so just use X5 Themes. And I actually tested it on my brother's H10 Dunno if that should be changed in the wiki, come to think of it. H10 and X5 WPS's, because at the moment, it only shows that it's for the X5, odviously, it works with the H10 however.
