Early upgrade for AT&T? IPhone 5S

So I really want to ditch my iPhone 4, and get the new iPhone 5s when it comes out.
While I was on AT&T earlier, I saw that I was eligible for an early upgrade for $449. Does this mean I can get the new iPhone 5s when it comes out for just $449 without renewing my two year contract? Or do I have to renew in order to get the $449 discount? I really don't want to renew my contract because I still have over 10 months left.

How to post to my secondary account on the tumblr app?

I have two tumblr urls and they both show up on the app on my iPad but I don't know how to post onto the secondary one, all my posts just go to the first one?

Is there a drop down menu on the post screen bit that should change it? The iPad app is pretty different to the iPhone or android app by the way

Thank you

My tumblr is bulba-bulbasaur.tumblr.com
