4.2, still waiting for the 4.2.1. Pondering just flashing it myself.... other then the "December" bug fix, have you guys noticed anything else?
Here is what I noticed.
-The Bluetooth seems to be better. After 4.2, my phone was getting disconnected from the Bluetooth Handsfree system quiet frequently. This seems to be fixed. I also listened to Youtube for a while with a BT headset, it was working for me.
-Seems like more widgets that can be added from the lock screen. I have NFC app and it appears in the list of widgets. (Not sure if this was there already). So maybe in future more apps will register/use this feature.
-When I loose the mobile network, it seems to get back to the network better than before. There were times I had to do the 'Airplane' mode On and Off to force it.
Issues:
-If I cycle the brightness in the Power Control widget, when i comes back to the custom setting, it seems to reset the screen brightness setting that I previously did. This was there in 4.2, its kind of irritating.
-The quick setting doesn't display my picture even though I have it in my contacts. When I click on it it brings the contact "Me" up with my pic. Signing into G+ also didn't help, I keep google+ disabled.
