Does the iPhone update when it is asleep? Only I have installed a data counter and whenever i wake my phone from sleep, the data shows as being used at that particular time. 'My data Mngr' shows the time down to an hour how much data used in a day, but always seems to show when it wakes even if it has been asleep for a few hours. Im sure it is not just updating when I wake it, but does anyone know how it works regardaing updating generally. Is at always 'alive'. Can it be controlled when asleep? In theory, if left on at night and asleep all night (phone not me), is it using data throughout the night? Always wondered how it worked. Is it the same for Ipad (I assume so) Anyone know conclusively?
