Upgrading iPhone 4 to iPhone 5?

I currently own an iPhone 4 on a $69 plan with Telstra which began in approximately June 2011. Obviously the date is now almost November 2012. I'm really keen to upgrade to the iPhone 5 and I was wondering if this is at all possible.

I've heard of people upgrading without having to wait the 24 months or whatever. Will I have to wait the rest of the time period or can I upgrade now?

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
