I don't know if anyone here has ever seen this, but it's pretty neat.. It's a TCPMP version .71j from 2006. It's not perfect, and it's older and lacking some of the newer features, but it's skinned! It comes with 1 QVGA skin.xml file that uses 2 .bmp files. I edited that file and along with photoshop, made that skin compatible with WQVGA for my Omnia.
I hope someone can take this version apart and figure out how to add the skinning feature into the newest TCPMP.

It's a winCE version I think... Don't know what the difference is, but it works.
