I kept seeing mixed messages about trading it in per their instructions (via mail, where they could indiscriminately claim your phone was in poor condition) or in the store (not allowed, or the credits won't process right).
I got my 4 iPhones by Monday 9/27 to my front door, and noticed the 4 trade-in return kits in my mailbox the next day. I rushed to the post office (making sure I put the right iPhone with the right kit).
3 out of 4 just got marked delivered today (the other should be shortfully too hopefully). On AT&T's site, they're all "In Transit". Hopefully they process and confirm by the end of next week.
Anyone had recent experience with how long it takes AT&T to confirm the trade-in and process credits once delivered to them?
