What do you mean by "WhatsApp Version of CoreDroid"? Are you wanting a Themed WhatsApp Messenger App using CoreDroid Colors (Blue, Black, & White) & the CoreDroid (CD) Logo? If this is what your wanting then I have a Blue & Black Themed WhatsApp & I can see about adding a few things to it or you can just use it and I can send you some Nice CoreDroid Wallpapers I.made and you can use them as your WhatsApp Background.
If you want to do that that would be great! Thx
