Ok man sorry if you missunderstood me. You know if this is not in themes and apps section willl be hard to fing. Search in xperia arc or another 2011 device and try it. The 2011 xperia are almost the same so if you will install xperia arc cm mod it should work. Remember to have backup. And meybe write in q&a section. There someone will answer you faster as most people use cm7, cm10 or cm10.1. So check first xperia arc themes and apps section.
Again sorry for my bad words completing.
