I'm not sure if someone has already mentioned this, but I was just checking on the website about in-store pick up and I found this
Can someone else pick up my order?
Yes for all products except iPhone. If you designate someone else to pick up your order, theyll need to bring the web order number and their valid photo ID.
If youve ordered an iPhone with a new wireless account or a new line, it can only be picked up by the account holder the person whose billing information is linked to the wireless account.
If youre upgrading or replacing an iPhone, it can be picked up by the account holder or by a person authorized by the account holder. Contact your wireless carrier to authorize people on the account.
If your iPhone is unlocked, it can be picked up by the person who placed the order or the pickup contact on the order.
I'm glad I found this because I was planning to go by myself and I'm not an authorized user, so I'm making sure they put my name on the account right now.
