I recently noticed on my at&t bill, that my iPhone connects to media net several times a day when I know I'm not using it (like at 2 a.m. or 6 a.m. when I know I've been sleeping and when I always have it in Airplane Mode with wifi off). It lists it in my data usage as Internet/Media Net Sent, and the size varies. I have seen it as small as 1kb, and as large as 900kb. Has anyone else had this problem, or does anyone have any ideas what is going on here? In addition to it being in Airplane Mode, I don't have any e-mail accounts set up, nor do I have anything set to auto-check. Sure, I'm not paying since we have unlimited data, but I still wonder what exactly is my phone sending even in Airplane Mode. Do you think it might just be that the times on the bill don't correspond with the actual time at which the data was sent?
