Yes, the contacts line up fine. It's just the card size itself.
I'm not sure if the 8/16 GB cards are half length tho. I know the 4G on the brand I bought was. I was willing to test it for $10.

Also, I've been running one of Fanoush's kernels for quite a while. Not sure if that's needed, but I'd say it's great idea to do so. :-) You can do that without changing your OS.
