    Hi all I'm trying to get a handle on multi-tasking on iOS 4.

    Do the apps that are in the multi task menu(double click home button) really run in the background so to speak?

    Let's say I use my gmail app to check email. That app sutomatically goes into multi task. What does that mean when it goes into multi task?
    Cause it seems like it's just a short cut so to speak, a short cut menu.

    It just pauses. If it actually "ran", the battery would drain extremely fast.

    Apps are not really running in the background. They are saved in memory, but do not use any resources other than RAM. They do not use battery.

    There are a few exceptions though. A developer can make use of background API to stream music, use location services, and a few other things. You'll see an icon on your status bar to know this is happening.

    Ok so my gmail app is not running in the background. Then what's the purpose of the gmail app being automatically put into the multi task bar?

    Most of the time, it's more of a recently used apps bar.
