Question for those that use the Docs in the Cloud service of iCloud. Back when the service was first demoed there was a seamlessness to the syncing that was going on. The guy updated a doc on his phone and by the time he picked up his iPad the change had already taken place. However, when I use it with my account I have to open the app, regardless of which device I am using, to get it to update. How does this work for everyone else? Does it update behind the scenes for you? Or do you also need to open the app to get it to update?
