2.2 is SUCKING! Phone lags with every action and it drains the life out of my battery. Apps that never ran are running no matter how many times I foreclose or kill with ATK. Like a lot of the other features, but I can barely get half a day out of the phone, whereas before 2.2, I could go almost 2 days with GPS, Wifi and bazillion other apps running or being used. If I knew how to go back to the other system(??) then I would try a reinstall of 2.2 before giving up. Thanks in advance.
