I have a 1 gig cellular data allowance on my contract, after that it gets very expensive. Im usually never over 1gig and haven't changed my surfing behavior after the ios7 update but now i feel the phone is consuming much more data, last month i went over 400 MB!! I dont have background updates activated. Is there anything else that consumes data in the background? Some Apps i use are zite, pulse, mailonline and digg - are those updating in the background?
