bogus data usage? - att

[brasswhite]

My data usage according to att website is many times higher than what I think it should be.
I've tried 3g watch dog, data counter widget and my data manager. They all say I use considerably less than what att suggests.
For example just last night att racked up my data usage by 40mb when I didn't use wireless data at all!
My wife's phone is an identical atrix which I setup for her. She get's pretty much the same amount of emails and we have pretty much the same kind of apps. But she doesn't have this problem at all.

I have wifi pretty much everywhere I go (home, work etc) so I suspect I should be using very little wireless data, but every month I hit my limit (200mb) so I turn off my wireless data for a couple days. Back when I had my blackberry I used the wireless data (google maps, browser, email) much more freely than now and I barely hit 100mb.

att rep says just try factory resetting the phone. Just wanted to know if anybody else had this problem.

Thanks.

Are you sure you didn't use any data? The only way I know for sure is to use APNDroid to shut off data.

Next how would doing a factory reset affect att's billing unless you have an app that's misbehaving.
