blackberry.net/cingular wap

[alicro]

Hello, i was wondering if anyone could answer a question for me- i have a blackberry unlimited plan through at&t, when i look at my online bill it shows data being sent to both wap cingular and blackberry.net almost every night at around 2am, when we are asleep and nobody is using the phone. There are no extra charges or anything, just large amounts of data being sent from my phone to somewhere - Does anyone else know why or where this data is being sent????
-thanks!

I have that appear also. I sometimes let my phone turn itself off at 11pm and wake up at 6AM. I then see a lot of data at that time. I am thinking it does some sort of reconciliation of data all at once. If they logged all the times I sent or received data during the day they would have to deliver my bill in a truck.
