I have the backup assistant turned OFF... the symbol still appears at the top and complete kills all data connection for HOURS. I'm in my house with 4G LTE service, and wi-fi and have not had updated tweets for 3 hours, facebook does not load, I haven't received email notifications for hours (although I've received emails on my computer), and my weather channel app still has the same "current" weather that it had hours ago.
I have to re-start my phone to get connection back! WHY!? ... this is the 4th Droid Charge I've gotten from VZN and there is always a problem!
