I just got this phone a couple weeks ago and other than a few times when it does something random for no reason, it's been okay. Suddenly, today, every time I try to do anything at all with the phone, make a phone call, open an app, anything, it says "The application _____ has stopped unexpectedly. Please try again. Force close." And no signal, no service, nothing. Any ideas? Nothing happened to it that I know of. I have tried rebooting it a couple times without improvement. Thanks for any advice. I am really perplexed.
