4th gen iPhone to be taller and include front facing camera?

iResQ has posted some pictures of what they believe to be the glass for the 4th generation iPhone. There are two notable differences from the current iPhone glass. First, it’s taller (1/4 inch) and it has an extra hole. Gee whiz, I wonder what we think that’s for; this extra hole in the glass certainly could be for an extra, front facing camera for video chatting. I won’t deny it; I want one, that’s for sure. But at the same time, I find it too good to be true. Parts like this aren’t that difficult to fabricate, so I’m not totally sold.
