How much would 4G LTE cost for an entire day on the iPhone 4S?

I just bought an iPhone 4S (unlocked). I was thinking of getting internet, since I'm going somewhere for one day. How much would 4G LTE cost for just that one day? (from AT&T)?
I mean just 4G (WHOOPS)
Not LTE

$0
since you can't get 4G LTE on an iPhone 4s

the 1st (and currently ONLY) iPhone that has 4G LTE is the iPhone 5.
