push-notification

How reliable do you find push notification on the iPhone to be? Does it improve when moving from the sandbox to production server?

I am testing (with the sandbox of course) and have found that notifications are often delayed or not received at all. I am not talking about sending multiple messages and only the last one arriving, as the documentation indicates, but any notification never showing up.

Also, I noticed that if I send a notification with an alert, and then send one with just a badge number, that the second notification will close the alert even after it's already opened. Does this happen between apps as well? For instance, if I send an alert for my app, and then the Facebook app sends a badge, will the Facebook badge close my alert window?
