Samsung will send the update to your carrier once it's ready. Then once your carrier makes the changes that it needs to, they will send the update out in waves to multiple devices at a time. don't worry and you should be getting it soon just be on the lookout. you can always try restarting your phone and seeing if the update will come up for you and the settings.

I'm on a Verizon variant and still on the June patch. I'm sure the carrier's and Samsung got the source code for it. it's coming... it needs testing and when it's ready, we will be notified of it when it's ready to install.
