Will the VZW model have full functionality on At&t or will there be limitations? If so, anyone have any ideas how to swap it for an At&t model other than selling it and using the money to buy another for my network?
It would work but I believe it is missing one of their LTE bands so it wouldn't be able to take full advantage.
Reach out to the person/company that you won it from and see if there is a way to switch it out to another carrier.
Act quick, you might be within the return period.
I gotcha. Doesn't hurt to call your carrier and see if they can make a special exception. People jump between carriers all the time and trade in their used phones. Explain the situation to a higher level of customer support or type up a nice letter. If that doesn't work, reach out to LG. The bottom line is that you want to use an LG product and continue using AT&T.I would, but I believe VZW was one of the sponsors, hence them giving away that model.
