Same here; I just noticed the notification of the system update this morning.
The thing is, I'm not sure I want to accept the upgrade. I also have a Razr Maxx and a Galaxy Nexus, both of which have versions of Jelly Bean, and all three are stock. Based on my experience only the Nexus does JB right. The Razr naturally has awesome battery life, but I felt it lagged pretty badly performance-wise. I recently flipped back over to the D4 from the Maxx and I've enjoyed the smoother operation, and now I wonder if updating to JB would mess that up.
Also, the browser in the Good For Enterprise app doesn't work in JB, and I'm not sure I want to give up that feature.
... Such a first - world problem....
