How do i get an update from iphone 4s to iphone 5? How much will they charge me?

YOU DON't NEED TO UPDATE. The screen difference isn't major enough to warrant a change. Besides, the speed increases are not that major. Besides, if you wait until your two year contract expires, you will save several hundred dollars. Wait until your current contract expires, or you will have to pay a large termination fee, and full price on the phone (which can cost $300 more than the subsidized contract version). Once your contract is up, just go to the store and you can upgrade. But seriously, wait for the next iteration of the iphone. It will be worth the wait.
