Device operating system releases are "released" by specific carriers once they have certified and trained their support techs, but still, you are able to load to any carrier's same model by following the instructions below.
See the link below, for the download and simple installation instructions.
Do a backup of your device first, using Desktop Manager > Backup. Close Desktop Manager upon completion.
