The carriers have the new version 0S 4.5 but they have not released it yet. I would suggest you wait for your carriers (approved) version as it will be a "clean" version and it will be supported. If you upgrade from somewhere else your carrier won't support it.
ALso keep reading this site, when they release it it will be big news!
