I didn't read through the whole thread, so forgive me if this is a repeat. Scottish Fold kittens ears stay folded down from kittenhood, and if they will straighten, they will be straight by 6-8 weeks old. From the looks of it, your kitten doesn't seem to have folded ears... I think the tips will straighten out. Some of Sneakers' kittens (and Sneakers is an unfolded Scottish Fold) ears did that, and it wasn't because she is a Fold.
Fold breeders typically classify their folds as single, double, or triple folded. Yours might end up being a single fold, if she is folded at all. The triple folded ears are the ones that are hardly visible from the front view.
In order for a cat to have folded ears, one of the parents had to have folded ears too. Folded ears don't show up unless at least one parent has them. As a sidenote, if you breed two folded ear cats together, some of the kittens will have congenital defects.
