Since IOs 6, iphone 5 and a move to Oranage /EE seems I am using more data than before Iphone 4 and o2. When it wakes from sleep seems to use +/- half a meg of date data as per 'My data manager' app (which is the same as my normal counter ion the phone, so I have ruled out this being wrong). Anyone else noticed excessive data being used more than before? Any one any ideas what may be dong it.All setting the same email etc. etc. Is there any app available whuich shows which apps are using up data?
