Unexplained Early A.M. Data Transfers
With all of the recent discussion about data usage and the threat of tiered plans, I decided to look at my AT&T bill in more detail this month. Imagine my surprise when I saw daily data usage anywhere from 1am to 3:30am. The transfer amounts range from 17kb to 4,546kb and are usually at the higher end. These are not just once daily. For example on 11/14 they occurred at 1:13am, 2:13am, and 2:30am.
I am never up at these hours, much less using my iPhone. Does anyone have any clue what could be going on here?

Sorry. I should have noted that mail checking is set to manual and the only notifications that are on are for ball games that end well before midnight.
If visual voicemail is updating, surely that happens more than 2-3 times per night and would update between 3:30am and 7am when I never have any data usage showing up. Besides, I have never gotten up and had a voicemail waiting for me.

Really strange. All of the early AM data transfer I was seeing was from looking at my usage online. I got my paper bill today and, even though there was daily early AM data - and often several times daily, little of it shows on my paper bill. In fact, no early AM data usage shows after 12/4. Why would it show up online but not on paper? Not complaining about it not being there, just trying to figure out what in the heck is going on.

This is from this month's bill. Next month I will take screenshots of the online details before they disappear so I can compare to the final printed bill.

This is not everything but representative. Yes, a lot of it is happening at 2:30am but can be from 12:30 to 3:30....and why does the transfer amount range from 1kb to 4,532kb?

I read once on here a while back, and hopefully Rene can confirm this, that the iPhone does update certain things while your phone and ONLY when your phone is being charged and in sleep mode. This was a while back but I remember reading about this...

Apple updates the phishing database when a phone is charging:
“Safari’s anti-phishing database is downloaded while the user charges their phone in order to protect battery life and ensure there aren’t any additional data fees,” Apple spokesman, Bill Evans, told The Loop. “After updating to iPhone OS 3.1 the user should launch Safari, connect to a Wi-Fi network and charge their iPhone with the screen off. For most users this process should happen automatically when they charge their phone.”
That could be the issue. Here's the full link:

Huge nocturnal data transfers
Also having these issues. I wanted to check my usage since I may upgrade to iPhone4 in November and wanted to see where I fell in data usage. My bill said last month I used 3.3 GB! But ever month before that was around 1GB. I had some HUGE data transfers in the middle of the night, here's an example:
07/11/2010 2:13AM Data Transfer Data 360 KB
07/11/2010 3:45PM Data Transfer Data 61 KB
07/11/2010 5:56PM Data Transfer Data 254 KB
07/12/2010 12:56AM Data Transfer Data 683,041 KB
07/13/2010 1:48AM Data Transfer Data 586,168 KB
07/13/2010 3:08PM Data Transfer Data 7,159 KB
07/14/2010 1:06AM Data Transfer Data 562,532 KB
07/15/2010 6:56AM Data Transfer Data 24,868 KB
What could be the deal?! I have Wi-Fi turned on, shouldn't that alleviate my data transfers most of the time?
