Don't listen to Sprint Zone. They don't have it set up to look at your device's software info and then determine if you are up to date. For most of us here it's more like a notice to let you know that an update was available but you already installed it. It was like this after my last update on the EVO 3D and after the September update to the LTE. That message hung around for over a month.
I'd love to be wrong here, but I will not hold my breath.
