iPad air using too much data.
New ipad air is using way too much data when tethered to my phone. It's wiped clean with nothing installed except a few browsers. Background app refresh is off. Ipad mini running iOS 6.x does not have this issue. I metered the data use and watched it (ipad air data use) skyrocket with no apps open except opera. Was not browsing. Opera said 1 meg was downloaded. However it used 15x that amount. Is this an ios7 issue?
iPad, iOS 7.0.4
