Works fine I did it a few days ago.

Again works fine.
And theres the Black dialer mod that should work; http://forum.xda-developers.com/showthread.php?t=850963
I'm about to try it.
There are a number of other theming mods not specifically for this ROM or device that work, like the keyboards Here; http://forum.xda-developers.com/show...p?t=754948with
and others I have tried with varying degrees of success, "Always before trying, Backup / Nandroid."
All of these mods will work if you have the right recovery (amend instead of edify), I have two post with a temporary/flash-able/cwm184.108.40.206 for amoled one is Here;http://forum.xda-developers.com/atta...3&d=1304009960
this is a work around for older scripting
Or if you don't know you have amoled or know you have a slcd
It'll take a few more steps but thankfully Doug Piston "Thank Him", has put up this page for us, http://dougpiston.com/?page_id=85 you will find directions for changing recovery's manually there.
Basically change your recovery to work with the mods then change back. I hope this helps you and a few others along the way.
Again "Please" always backup first...
