The reports of 300 page bills prompted me to log in to the wireless.att.com site and check my settings. While I was there, I confirmed that I'm properly set up for the unlimited data plan and such. I don't expect any surprises during my next bill. Anyway, while there I called up a list of my data usage - indeed, each session was listed on its own line. What really caught my eye was 3,682kb today at 1:01am, and another 5,407kb at 1:35am this morning. I was asleep and the phone in stanby, and I did not receive any emails at that time. Wifi should have been the active network connection, not EDGE, since my router is always on. There was another 1:01am transmission for 1,1718kb a few days prior, on the 10th. There are other at-or-around-1:00am data transmissions that I'm pretty sure I didn't initiate. I wonder what's going on? Over-the-air iPhone updates? Anybody else have similar data sessions when they weren't using the phone?
