Is there a way to turn off some of the items that are in the cellular data area? I've tried this several times over and over again...sliding the tab button to the left so the green is no longer there to some of the items that I don't want on my cellular data...for instance...I have no music on my iPhone whatsoever so I turned that off as well as my facetime because I don't use it...and the stocks I don't use...there are a few more items I have turned off also...but when I go to reset it and it clears everything...all the items I had turned off are turned on again. I can't seem to keep them turned off in the cellular data. Is this not possible
