I got a text from my carrier today that I was getting close to my monthly data limit (which I've never come close to), so I finally took a look at the settings on the phone for reviewing usage. What's weird is that if I go to the Data Usage section within Settings, the initial indicators says I've used "0.00 MB".

If I then open the Billing Cycle section, there's a field for "Amount of data used", but that's an entry field -- tapping that just allows me to enter a number, which doesn't make sense.

If I go into the "Cellular data usage" section, then it's accurately reflecting what I've used.

What's strange is that all of notification options appear to be tied to the "Amount of data used" rather than "Cellular data usage" -- isn't that pointless if that field is user-entered rather than system calculate? What am I missing??
