iOS 7 using too much data
I have an iPhone 4s. When I updated to iOS 7 it started sucking so much data I almost reached my limit in 10 days. It was using all this data in the middle of the night while I slept. I have turned off cellular data for everything, turned off pretty much everything so the only thing my phone was good for was phone calls. It worked, but that's not why I have an iPhone. The next time I talked to support they had me reset my phone. That did not work either. My phone is using upwards of 77000kb at like 1:30 in the morning while in my house hooked up to wifi. Am I the only one having this issue? Has anyone else dealt with this and found a solution? I am at a complete loss as to why my phone is doing this. It never happened before the iOS 7 update.
iPhone 4S, iOS 7.0.3
