I still don't understand why people won't let go of the whole, carriers deploy updates. They haven't in more than a decade because device manufacturers got tired of carriers messing up their devices!
The updates come from Samsung directly! Usually South Korea gets the update first, then the US firmware devices. The rest of the world varies. Canada's W model usually falls somewhere further down the line. Then you have staggered rollouts so not every device running a specific firmware will get the update at the same time. A good example of this is, T-Monile USA usually gets their updates before AT&T and Verizon and TMB U are usuallt the only carrier firmware allowed to participate in most beta releases.
