Can you acess tinypic or imageshack on a iPod? If so, I guess you can upload there, sorry if not, it's just... I never had an iPod or similar, so, I'm very ignorant on this matter.
What do you mean by half and half? Half litter is banded and the other half not?
Some white markings on the belly, neck and nose are allowed on the self variety (black is self), not too much though, like, all the belly, I guess I'll never be able to tell you without a photography.
Cinnamon is very different from Dove, Dove is self, Cinnamon is agouti, but they both are related though, Cinnamon is a mutation, Dove is a combination between two mutations, the Cinnamon and the Black, so yeah, the Dove is related to the Cinnamon and Black, Dove is actually my favourite color.
This is a Dove:

(Ignore the white fur, it's the pattern banded)
And this is a Cinnamon:

The Cinnamon girl I found is also Umbrous, so, it's normal the difference and she is a bad example of the color, this photography is one of the bests I've seen, amazing agouti markings.
