I did a quick search (and mulled over that big, pinned battery performance thread) and couldn't find much. So, on a Touch, will applications such as Mail still try to push/check for new data when there is no WiFi signal found or WiFi's been disabled? Or will apps with Notification pushes see there's no WiFi and not try? In terms of battery performance, it'd be a right bother to have to disable WiFi, and disable Notifications, and disable Mail pushes and disable any Jailbroken app pushes when what all should be necessary is to disable the WiFi. Any idea?
