Hey guys, i just purchased the iPhone 4S and i feel as if i made a mistake with the new iPhone 5S/5C coming out very soon. I feel as if the 4S would be very slow/feel outdated by the end of my 2 year contract. I'm thinking about trading it back in for the Galaxy S4, only because of the fact that i wouldn't have to pay anything for it and it is much newer. What would you do?
