So I have unlimited data on my ip4 and until the last few months I rarely ever came close to hitting the 3gb soft cap. For a couple of months now I am using a little less than 4gb per month but nothing has changed with my apps or really how I use them. I stay connected to wifi when it is available and I do not stream media while I am off wifi. Does anyone know of an app (iTunes or Cydia) that monitors the data usage per app? I have found some that monitor the entire usage but that is not what I am really looking for.
