Once you connected the phone to your computer, did you open up Samsung Kies?
If so did it not pop up anything? My Kies needed a update before giving me the firmware update for my phone. It could be that Kies needs to be updated before the update gets pushed out.
Some have gotten the update via OTA but some of us need to get it from the Kies. Also some are reporting they did not get the update yet. This could be due to regions & Cities.
I have noticed I have an "N" hovering over my Software Update shortcut, but everytime I click on it, it says no updated available. Why is this, and how do I get it to update?
