    Iphone 4s Data Usage Instead of WiFi Usage


      Can anyone tell me why my iphone 4s is using large amounts of data when not being used, is in my home with wifi turned on and available and often occuring at night? Thought wifi usage preceeded data usage. Is there any way I can find detailed billing to see what applications are using these large amounts of data and how to prevent them or prevent them using data over wifi? Interesting that with two iphone 4s's only one seems to be having this problem.
