I have been home sick since thursday and will probably stay home all weekend. My iPhone billing cycle ended Aug 12th at midnight I am sure and started again on the 13th. When I logged into my ATT wireless data app Friday morning the 13th it said I had used .25. I don't see how I could have used any data whatsoever since I went to bed and then checked it in the morning. So I decided to check it again this morning and now it says I've used .83mgs. Again, I have not been out of the house and I am connected to my Home Wi-Fi so where is this data usage coming from. I will check it again tomorrow morning and see how this is progressing but this has me concerned since I just downgraded my data plan to the lowest 200 mgs a month since I an usually always connected to wifi but if this continues I can see where it might take 10 mgs a month and maybe even more. Does this sound about right?
