Samsung Omnia i910

I'm sorry if this question has been asked before.

I am looking for the non-branded Windows mobile 6.1 OS. I have no idea if one is even available, but if so does anyone know where I can find one? I'm just looking for the windows mobile 6.1 without all the samsung and verizon crap bundled. I would prefer to get it from either microsoft or samsung if possible. I'm still not 100% comfortable putting someone elses 'cooked' rom on it.

Thanks in advance for any help.
