vr .09 and .10 is not a baseband. its a model version. .10 is the newer model version. it could be as simple as changing a sticker, or as big as a higher binned processor/ better radio/different screen/anything.
....haaaateI am on .10 phone is perfect. I had 2 .09 phone both dropped calls and data. Also the .09 ate my battery much faster.
I kept the nexus phone because it seemed to be head and shoulder better than my first 2. I noticed the difference with in 10 minutes
