So I participated in a web conference on some enterprise software. The company I work for is looking to go with a software partner for some expensive software, so I logged into the webex meeting. At the end, they said (to my surprise) that they were giving away an iPad mini to one lucky participant. I've never won a thing in my life, but lo-and-behold, they pulled my name out of a hat. I got an email later that said they were sending me an iPad mini (black, 16gig base version). I was skeptical until they forwarded me the Amazon confirmation with tracking. It will be here on Wed. While I'm happy to have a free base mini, I really would like to pay to upgrade it to a 32gig LTE version. Will the Apple store entertain an exchange + payment on my end (obviously) for a sealed mini from Amazon? I really hope so. Thanks.
