Here are the issues I've had since the pushed download.
1) Moderate to severe lag time moving between screens.
2) Takes about 10 seconds for home screen to load after returning from an app
3) No internet connectivity. Home page begins to load and just stops.
Weather apps work fine, FB app works fine but slow to load.
Talked to Verizon, no way to reinstall Gingerbread.
I should have said that we did everything they could think of, including a battery pull, restart, removing SIM card and removing memory card. We also removed A few apps including Norton Security. About the only thing we didn't try was a Factory Reset. I guess that's next.
