So far I have enjoyed the update. I had my Thunderbolt right out the gate. (never new it was the day it hit market, I just needed a new phone company as Boost sucked) Anyhow, the first update I was not impressed with, but GB is definitely user friendly and seems much more stable than previous builds for the phone. My remaining concern is battery life... I am about to upgrade to the extended battery... sadly this is something that should have been addressed in the development stages of the phone.
