Not sure if this has been posted, but those of you with no charge/tracking yet. This is what I did yesterday.
I went online early in the morning to
https://reserve.cdn-apple.com/US/en...1&sourceID=email&rv=0&path=&iPP=U&appleCare=Y and reserved a 128GB Plus Matte Black VZW at my local store. It is the Iphone Upgrade Program reservation link, because the regular consumer reservation link does not seem to have stock. I kept my pre order open until I met with a sales person at the apple store. I told him I wanted to do the VZW Device payments instead of the Apple Upgrade program. They said no problem and they could do it. So I went on my iPad, cancelled my pre-order right there, and he processed the upgrade on the phone with no issues!
I was worried because going through the IUP reservation link, they would only allow me to pay for it that way, but you can pay anyway you'd like!
Hope this helps some of you!
