No--not one resolution that I've seen.

I've combed through forums on this site (there are few referencing mystery data usage), forums on Apple's site, comments on a lot of the "techie" websites....every person gets the same thing, the explanations in my first post.

The early morning transfers haven't stopped, but they have gotten smaller since I've filed two official complaints...a little odd?

My only course of action, I suppose, is just to continually monitor the data and complain if they charge for overages again.....until the new iPhone comes out and I can switch carriers?
