How long does it take for at&t to activate my iPhone 5?

I ordered my iphone 5 9/29 and have a hard time thinking about it these last weeks, and last wednesday i received an email from at&t that my iphone 5 is on shipmnet process and they gave me a tracking number so i tracked it every hour, finally when i woke up this morning it says that my iPhone 5 is already shipped in the store but still there's no call or message from the at&t store that i ordered in, that i can pick it up in the store so i call them and the lady said that iPhone 5 just arrived and they'll be working on it… Now my question is how long does it take for me to wait so that i can pick up my iPhone 5 in the at&t store? And i understand if they'll still activating it, etc. But aren't they call first the owner of the iPhone 5 before activating its sim, or like opening the box? And how long will they work for it to activate? Does it take day, days, week? And can they give me a call tomorrow to pick it up even tomorrow is weekend (saturday) or ill wait for monday to come? Sorry for my english but we just moved here in USA just months ago and don't have any idea how system works here. I'm just really excited for my iPhone 5… Thanks btw i'm 16

Added (1). I ordered it in the at&t store and the email that i received from UPS store that says the store received it 11:18AM this morning… I already suffered 4 weeks and 20 business days of waiting that phone… I heard that news though thats why my order info last week is back ordered but now its already in the store just waiting for a call and message from them…

1-2 days after you unwrap the package. Most mail order advises 6-8 weeks for shipments to arrive. A few are getting faster, but not AT&T.

Go to the AT&T store tomorrow and see if it is ready. You'll never know until you go there. They may not call you cause they are busy. I don't see what they have to do to it to make it work. All they'll do is give you the box and the sim card, put the sim card in and it will work. What you waiting for? Go get it! Have fun with it.
