Mysterious Data Usage in Middle of Night

Each night, between 1:00 AM and 3:00 AM, I've noticed data usage of approximately 20 MB's. As a result, I've been forced to upgrade to the 2 GB plan, which I'm OK with, I guess. However, 20 MB's times 30 days = 600 MB's! That's over 25% of my alloted usage for the month, completely NOT on my behalf! Ouch!

Unfortunately, in my line of work, I cannot simply turn off cellular data or turn off the phone entirely (as instructed by AT&T). I need to accept emails at anytime, day or night.

When I setup my phone, I specifically opted out of sending diagnostic data to Apple, in order to avoid any erroneous data usage.

Is anyone else noticing this? Is there any way to avoid this?

Thanks!

Probably AT&Ts way of saying, "Hey cheap F*, sign up for a better plan, or were just going to keep using up all your data on you."

i wonder if it has anything to do with iAds thats in os 4? you can try opting out by this link and see if it will stop the transfers

When does the phone go into standby and how does that differ from sleep? Is it in standby when it is locked (either automatically or by pressing the lock button)?

You posted to a thread that's almost 2 years old. I suggest starting your own thread so it will get better visibility.
