A followup. Multitasking is not like on Windows of OS X. Apps do *not* keep running, using CPU cycles, in the background. Here's a great explanation of the whole thing:Originally Posted by Dennis*G
OK, how do we get apps NOT to go to background? Every app I open is going to background process, and I definitely do not want that, [...]
Here's the long and short of it. When you are running an app in iOS 4 and you press the Home button once to leave it, the app doesn't quit. Instead, it goes into suspended animation, like the scientists in cryogenic hibernation in "2001: A Space Odyssey." The app simply stops receiving events from the system; its run loop isn't looping. The app is both backgrounded and inert; but it is still running, in the sense that its resources and interface are still present, so that it doesn't have to be relaunched from scratch in order to resume. That way, when you come back to that app, no matter how, the app can simply pick up doing what it was doing when you left off, instantly.

I just looked at my exchange calendar and everything is there back to two weeks ago, if I look back further then two weeks, everything is gone.
So what does this mean? I connected to my work calendar, which I assume is Exchange. I've not noticed any problems. Should I disconnect or risk breaking something?Originally Posted by mattCR
I haven't tested, but across a lot of my admin boards is a warning to staff to not upgrade to IOS4, because it breaks MS Exchange Calendar connector.
