I just checked apple.com the iPhone 6 is shipping between 7-10 days and the iPhone 6 Plus is 3-4 weeks.
I thought about cancelling just now and going with Apple, but now I'm seeing a different estimate. AT&T is saying between the 13th and the 15th, which doesn't seem bad at all, I don't see apple doing any better than that. Wonder how accurate that will end up being.
Looks like I might not be able to cancel now if I wanted to anyway.
