Just got off the phone with AT&T after I got a message about data overage on my account. I received an E-mail that there was 430Mb of data used during the night while I was at home asleep. AT&T's response was that all smart phones receive automatic updates. I told them about all app installs requiring approval and they said that the manufacturer or Google could have pushed the update. So basically they are blaming Google or Samsung for 430Mb of data used in one night on my device. Total data usage per month max on this account in the past 3 months has been 39Mb since I am connected to wireless 90% of the time (both at work and at home). They offered no other solution than recommending I switch to a higher data plan. This is a failure on AT&T's Customer Relations (or lack there of) in my mind and a warning to anyone considering a Android on AT&T! Watch them carefully or they will get their overage charges out of you.
