Sure. Someone else might have a better explanation of how things work. Meanwhile, think of the Kindle and the iPad needing to "talk" to each other, to tell where each stopped and needs to pick up. Without Whispernet and wi-fi / 3G on, they can't communicate. Of course, you don't need to have Whispernet and wi-fi / 3G on the whole time you're reading. It just matters when you stop and start.
