This may be a stupid question, but I preordered my phone last night via the Apple Store app. I'm with AT&T. At checkout, there was the phone, the Apple care, the "upgrade fee" which it listed as "one time charge," and then something like "smartphone fee" or something like that, $30 which said would be monthly I believe. I do remember paying a little more a month when I got my first iphone (the 4 back in 2010) but I don't remember my bill increasing by *$30* when I got my 5. Am I not understanding this right? What is this $30 smartphone charge?
