The black carbon skin has been available for a long time. The black titanium one is not on sake YET. It should be very very soon though.
What do you mean by "choose between the old an new one?"

I am not talking about the black titanium
dBrand has posted (on their FB) that there will be a new version of black carbon fiber skin, which will look "darker" than the original one
Go to their Facebook page and check it out
