Wow this is definitely not okay. Has anyone tried sending an email to Steve Jobs. I bet if a few people did, he'd reply to at least one of the emails.

Interesting update to this. There's news that a class action lawsuit has been filed against AT&T for overcharging iPhone users for data usage.

From The Atlantic (which I will link to below): "Retained by plaintiff Patrick Hendricks, a representative from an independent consulting firm visited an AT&T store, purchased a brand new iPhone, and then disabled all location services and push notifications. All of the applications on the new iPhone were closed, no email account was configured with the device, and it sat untouched -- the plaintiff claims -- for ten days. 'During this 10-day period, AT&T billed the test account for 35 data transactions totaling 2,292 KB of usage,' Courthouse News Service reported. 'This is like the rigged gas pump charging you when you never even pulled your car into the station.'"

I also had this issue, with my data doubling every month (300-750-1.5-2.0gb). After doing some research, I found that my internet calendars (I connect to 3-4 Google Calendars, and a TripIt calendar), were set to fetch sync every 15 min. Between that data hog throughout the day, there also appeared to be a massive draw at about 1:56am every day. Setting GMail to Fetch (15 min), my Exchange server to Push (email only - I use gcal sync on the desktop, and then link to the gcal) and my calendars to "Manual" has reduced my 2gb limit to approx. 140 mb TOTAL over the last 9 days.

Hope this helps.

I'm thinking the guy from the Macintouch link is right: It's starting to look a LOT like diagnostic reporting after all:

This weekend will confirm it for sure.

I still think everyone is blowing this WAAAAAAY out of proportion. I use my iphone on 3G and not wifi A LOT during the workday between streaming music, email, facebook, twitter and I NEVER have more than one or two lines of usage per day when looking at ATT's website. My wife's data usage also is consistent with her usage and displayed on one or two entries a day. I think ATT's inconsistent manner of grouping and displaying data usage per a day is causing this confusion and would confidently say that whatever is left gets dumped into one huge datapoint/bucket. Asking ATT isn't going to do anything because most of the people we talk to don't have access/don't understand how data usage is being captured on our iphones.

Did some digging now that the wireless portal is showing details again:

Before 6/8 -nightly upload was ~1-2MB, as far back as records showed (to mid May).
6/9, was 6 MB.
Then, after 6/9, every nightly connection was ~20MB!

Again, no major change in how the phone was being used. This is crazy.

Oh. My. THANK YOU iOS4.

I'm ready to close this thread.

This is silly look at your bill, the iPhone has a trickle data connection that stays connected almost all day. That’s why you normally only see 1 or 2 charges for data on a single day. That’s why you never have to 'wait" for 3G to connect like on older smartphones.

Your phone isn't using data in the middle of the night its just reporting the usage.

I noticed a "feature" of iOS4 is that the phone will use wifi in sleep mode. Evidently the phones currently switch back to 3G mode when you are not actively using them.

This is being discussed on Macintouch as well:

www.macintouch.com­/readerreports­/iphone­_touchplatf...

"I had opened a case with AT&T and I just talked to a manager at tech support there and have some very interesting information to report. He said that when you register your phone there is something that you check where you allow Apple access to it, and no way later to turn this off. Apparently these data transfers are coming from Apple! They have increased in the last few months and they have gotten some tech support calls about them. He said they are trying to resolve the issue with Apple, since these transfers in the middle of the night *will* be billed to you and affect your data plan."

Will check tonight

Weird. What are the settings on her phone? 20MB is quite a lot and I can't imagine what it would be transferring. Does she have email settings setup to check email once a day or something? Also, is "data roaming" turned off in the network settings?

I think it's something to do with AT&T. I had the same situation at about the same time as well, though only every couple days rather than every day. I asked AT&T about it and they had no clue. What I have noticed is that after unlocking my phone and moving to Tmobile, I don't have this mysterious data transfer while I'm sleeping.

This is crazy! I totally have this to on my girlfriends phone. Some nights up to 60MB!

I was finally able to access my AT&T data usage history today and noticed nothing out of the ordinary. No erroneous transmissions in the middle of the night! Crazyness. I was half expecting that.

Here's my last few days of data usage:

Until it's resolved, any affected users should enable WiFi (if they have it) so their phone uses that over cell data, or turn off / airplane mode the phone overnight. The latter is less preferable if you expect calls at night.

I doubt this could be it, but I am throwing it out there.

Where are you? Post location. I looked at my past bills, and saw absolutely no data charges at the times indicated, and everything checks out. (text plan= 200, iPhone 3G)
