I think the updated radios affect depends on what hardware revision you have and where your phone was made. My first GN was made in China and had the radio revision 10 at the end. This particular unit was not able to stay connected to 4g for more than 3 min, constant drop calls and what not. Returned the next day. Second brand new phone was made in Korea and had the revision 09. And with every radio update since it's had better battery life and no signal loss. Now I could just be speculating but that's my 2 cents.
