Rosiega,
If you go to AT&T's online forum and read the experiences of those who have ordered through them, it will help you decide if you want to buy it elsewhere. They have the longest wait of any carrier.
I initially ordered my 6+ 128G Silver from the AT&T store on Oct. 17 and was told by them it would be 2-4 weeks to deliver...well..When checking the online order status the next day, the *estimated* deliver was Nov. 17- Dec. 3...On Nov. 15, the status then changed to Nov. 28. - Dec. 10. After lots of research online and reading about others REAAAALLLY bad experiences with AT&T orders, I called AT&T to try to get a straight answer. First I was told they were back ordered. Then was told I should get the tracking number any day.
I finally decided, based on so many people's problems with long waits, inaccurate info, etc. from AT&T, that what was likely to happen is that on Dec. 10 - the last day of my shipping window - that it would probably get bumped to the end of Dec. and into January!
Yesterday, I called and cancelled my AT&T order and called Apple to order through them!
What a totally different experience! The guy who helped me was amazing and even got a 3 way call going with AT&T to fix an AT&T mistake.
One of the many things I appreciate about Apple is that they under promise and over produce - especially with estimated shipping times! I expect I should get the phone in about 2 weeks.
This was such a terrible experience with AT&T and from everything I've read, they have LOTS of very angry customers who are totally getting the run around on these iphone 6 orders. The customer service is a joke and every rep I spoke with blamed ALL the issues on Apple which, of course, is not true! Apple has no control over how AT&T chooses to fulfill the orders of phones they receive from Apple. People who ordered phones in September are still waiting for their phones...those who ordered later than me in October (same exact phone) received their phone already so their is no "line" in which those who ordered first get their phones first, etc. It's a big, disorganized mess!
My advice is, if you are with AT&T, DON'T order your phone through them - get it from Apple!
