The website that showed me the most updated information is

I got my email and text message at least .5 hr to 1 hr after I saw the status on these sites.
Hope this helps as I know how eagerly we all are waiting for our phones.
I pre-ordered my 6+ on 09/12 and don't have the phone yet and for my husband, I got the 6 right on 09/19 from AT&T corporate store when I went to check JUST IN CASE they have any 6 or 6+ left at lunch time
