Data plan has sky rocketed!
I have an iphone 5 and upgraded to iOS7. Since doing so, my data plan has sky rocketed. I turn off apps, and have wi-fi turned on when i'm at home. Since the upgrade my data has more than doubled. Is there a fix, or at least a suggestion? Also, the battery life is horrible since this upgrade too. Is there such a thing as an undo? Ugh!!
