Hello there, Macrumors forums. 
I saw the 5S and was intrigued, so I dialed the upgrade number for AT&T and they said I am eligible for an upgrade.
I am also planning to sell my excellent condition iPhone 4S to Apple. What is the total exact cost for buying a 16GB iPhone 5S on an upgrade?
Thank you,
LPDAL
