I just upgraded my iPhone to OS7 and in 2 days have used all my data
I just upgraded my iPhone 4S to OS7 and in 2 days I've used all my data (I'm on a limited plan due to having multiple lines on my phone plan). I never had problems staying within my old data plan before. I only upgraded because I was told to reset on my Macbook to get rid of a glitch in my operating system that was draining my battery after 4 hours. Unfortunately, it wouldn't let me reset until my iTunes was upgraded to OS7. So now I am stuck with an operating system I don't like, that is somehow using all my data, and still gives me less than one day's battery life. I've tried turning off as many things as possible but don't know what's using the data. Any suggestions?
iPhone 4S, iOS 7
