So, I have owned an iPhone 6 since launch day and bought an 6 plus a month ago and used it for a week or so before returning it, but now I regret that. I miss the screen and the battery life, and using it with one hand wasn't as awful as I though. The only problem is, I used an upgrade from another line to buy it, and now the AT&T store where I bought it is out of stock, and it says online it will take 28-35 business days for it to ship. The Apple Store has all models in stock of the 6 plus, and I was wondering if they could do upgrade swaps now? I know in the past they could not, but I read somewhere that wasn't true anymore. Anyone know?
