Galaxy Note Extended Batteries and Cases
Sorry to resurrect a slightly older thread, but I found some answers and wanted to share.
So I own two Galaxy Note International N7000s and just bought one AT&T i717.
Yes, I can confirm that, for whatever reason, the batteries are just slightly different in shape. I have no idea why. As a result, you need two different extended batteries for each one, you can find them on Amazon from Hyperion, and they're both clearly labeled as to which battery fits which. I've bought both, and they all fit their intended models just fine.
Like many of you, I was looking for a case for my Notes with extended batteries, and I could only find one for the N7000:
It seems that there are none for the i717.
But the good news is that this case DOES fit the i717 AT&T Note with the extended Hyperion battery as well. It holds on snugly, and is fine for that model. There is some air space inside, because the AT&T Note has a smaller battery protrusion and so it doesn't perfectly match the curvature of the case (which is larger) but you'll never notice that, and this is far better than carrying around your Note and extended battery with no case! I bought the red version of this case which is on my i717 AT&T Note, and is just wonderful! It feels so much safer than a Note with no case. So, speaking just for myself, WOULD BUY AGAIN EVEN FOR THE AT&T NOTE!!!
I posted similar information in the product reviews for the Black and Red versions of the case, just to try to help.
