I was planning to purchase an iPhone 6 today via the Apple website (to take advantage of their support of World AIDS Day and receive the $50 AT&T discount before it goes away at the end of the year); however, I only saw options for the AT&T Next 12 and 18 plans. I was hoping to go with the Next 24, but didn't see this option available. Has anyone else run into this issue? Am I doing something wrong, or is the Next 24 plan only available directly from AT&T? Many thanks in advance for your help.
