I just bought an LG Nitro on 3/16/12. Starting yesterday Social+ does not refresh properly and my gmail app does not work. It says "The app GMail (process com.google.android.gm) has stopped unexpectidly. Please try again." Also, next to the 4G emblem at the top there is an emblem that is 2 arrows in a circle. What does all this mean. This is my first droid and so far im missing my iPhone.
