Can a Minor Sign for a Package from UPS?

I ordered an iPhone from Apple yesterday using my mother's credit card, but the name of the recipient is me and I'm only 16. She will be at work when the package arrives and I was wondering if I can sign it.

If you have ID, that would be helpful. Chances are good that no signature will be required and the package will be just left. Because it is small, it will probably be delivered in your regular mail rather than the big brown truck.
