Late att night

We (my significant wife and I) have just discovered that AT&T cellular does a thing of which we were previously unaware.  That's a little redundant, isn't it.  Oh, well, never mind.  Moving on.

You see, late at night, a little after midnight, AT&T will access your phone and download a summary of your phone's data activity.  I had vaguely assumed that they kept a running total, but no, apparently the phone itself keeps the record, and then AT&T just grabs it in one go at a time when most phones are not in use.

Unfortunately, if you've accidentally left a few applications open for a long time, and also coincidentally forgotten to turn on WiFi, this download can end up quite substantial.  Of the, "Hey, where'd all my data go and why am I getting overage charges" variety of substantial.

So let this be a warning-- close out your apps every once in a while.  And don't turn off WiFi and then forget to turn it back on.
