I have a Verizon Nexus and as soon as I saw that Team Liquid ported the GSM code for ours, I snatched it up. I've had 4.1 for a little more than 24 hours on my phone w/no major issues. (Had a couple small ones, totally my fault though.)

I really enjoy the new notification system. It's very fluid and helpful. One thing I noticed straight away that wasn't mentioned was that after I flashed my phone, signed in and started resyncing apps, the "app1 was installed" notifications didn't fill up the top of my phone. In fact, as soon as it finished, it disappeared! I got other notifications for emails and texts as my stuff synced to my phone, and they weren't jumbled in the mess or accidentally cleared by myself.

The new notification set up is just the top of the jelly bean pile...it gets way cooler as you use it!
