In the future, if there is an update to the AT&T version of the S4, how will it be delivered? OTA? Something called Kies?
If it is delivered via Kies, would it be a good idea to backup all apps and associated data before I perform the upgrade? Or is it like an OTA update in which the update is applied over the top of what's already on the system?
