Been running this now for a few hours on my Verizon GN, and this mother is fast! No slow downs, no lag, no hiccups at all! Well, maybe 1 hiccup... WiFi range has been cut in half, but it seems to be an issue with many. Not worried though, I'm sure we'll see a fix later today.
If you have a GN and its not rooted, root now! If you're rooted, go flash this now! Google did one hell of a job with this one boys, and girls. Right out of the gate this will blow your mind!
