my droid is lagging so badly i dont know what to do next..... i have had to revert to regular wall paper just to get the phone to do something. i have to reboot the phone 3 or 4 times a day and most times the icons and widget do not come back and i have to reboot again. do you think i need to exchange the phone? or is there something i can do to help it get back to the awesome thing it once was?
