The last 3 days my daughters 6 has chewed up a huge amount of data, for a total of 7.5 gb this month. Her usage is usually under 2, and the phone is always connected to wifi when home. After getting an alert text from att, I checked the usage on the website and I see strange times data dumps the last 3 days, occurring at specific intervals. 12pm, 3pm, 6pm, and 9pm all using 0,5 gb to 1 gb. I've turned off a bunch of cellular data relating to iCloud and itunes/App Store. Anyone else run into this?
