I don't have any information about different colors of the cover, or any alternate places to buy it.
I do, however, have my own question about the cover: how does it stay closed? Is it magnetic? If it's not, I don't see how it stays shut. Also, when you open the cover the back on itself, is there any way that it will stay in place?
I know it's only $20, so I shouldn't be expecting too much, but I waswondering if anyone knew anything about it.
