I just got my iPhone 5S yesterday and before setting up the phone I backed up my iPhone 4 to iTunes. I then plugged in my iPhone 5S to back up all data from my iPhone 4. Question: Why is my cellular call time lifetime is same as my iPhone 4 at 2 days and 23 hours. Shouldn't it be 0 since I have not used the new iPhone 5S to call anyone yet? Thanks for any answers.
