iPhone 4s excessive cellular data usage

Sunday morning, I got a warning text that I had used over 90% of my 2GB cellular data.  I was surprised at that, so I dug through the information, and found something I can't sort out.

I've been using an iPhone 4 since they first came out.  I pulled up my data usage with AT&T online, and over the past year, I have an average data use of 285MB per month, and a peak month of 443MB.

I upgraded to a 4s on October 14, and between that date and November 5, AT&T says that I've used 1967MB in that 3 week span.  I'm using the same apps on my phone, no iCloud synchronization, email set to manual fetch not push, no tethering, I don't listen to music or watch videos on cellular (and rarely on WiFi), and yet somehow I'm suddenly using 6 times more cellular data as was typical before?  My WiFi is set up correctly as home, as I do see the phone switch over to it.  Even then, I mostly use my phone to check email, FaceBook, and text.


Things went particular out-of-whack last week, with 414MB on 10/31, 640MB on 11/1, and 687MB on 11/3.

According to the cellular usage in my phone, I've sent 27MB and received 225MB in the same time frame.  I'm included to agree with the phone, as that number is consistent with my standard usage patterns.

I expect some discrepancy between what my phone says I've used and what AT&T says, but 252MB versus 1967MB?

I spent over an hour talking to Apple looking for possible explanations, but the phone was already set correctly.  They handed me off to AT&T, but AT&T only told me that they just know how much data is used, not why, and couldn't explain things.

I've seen a few messages suggesting similar problems.  Has anyone seen similar issues and gone back to try to explain it, only to find similar major discrepancies?
