I was wondering if anyone could set me straight here as I have 2x 3G iPads and they both show up with data usage on my carrier's daily usage report even when I havent used them for days. During this period they are asleep (not totally off). I was wondering if anyone else had seen this, and perhaps could explain it? The data amounts arent huge (<50kb) but I would like to know how to stop it if possible without having to fully shutdown the devices. (they are business iPads and I need to track usuage but these little data downloads/uploads make this hard for me.
