If you close magic jack app and it's not running in the backround then the pod touch 4 wont' ring right?

Question

   I might have put this question in the wrong catergory if you think it would be better asked in the app category please let me know but I know this is the general board for most main questions.
    HERE'S WHAT I READ"
   Most of the apps showing in the Recents tray are not actually running. Very, very few apps are doing much of anything in the background. The only ones that are likely to be draining your battery would be apps that play music or access location services. Unless you're noticing unsual behavior from the phone, it's not really worth the effort to go quitting everything. Last time I counted, I had about 80 "recently used" apps showing.  I have no issues with battery life.
   So if if I have Magic Jack open and I just hit home button once then it will ring but if I close it by double clicking the home button and deleting it to close it would it still ring?

Answer 1

   Thanks for your response IIIaass,
   I have a couple of questions, I was under the notion that when you simply clicked the home button once the app is closed but I've heard different.
   1)   So if you have an app open and you click the home button once and the screen shuts down it's still running in the background right. But to close the app completely you have to click on the home button twice and then the the screen raises up and you tap on the app until it jiggles and you see the red minus badge and then you delete it this is closing the app completely right? Or does the app close when your viewing it and just click the home button once and the screen shuts down it would be still running in background?
   2)  So let's me see if I got it straight. In order to close an app you have to double click on the home button tap until it jiggles and tap the red minus sign badge and then that completely closed the app? Am I right on that
     Also as long as you have notification turned on you can close the app completely by double clicking on home button and delete the app to close it and Magic Jack will still ring even though the app is completely closed because I didn't know if it had to run in the background in order for a call to come through and ring. But from what your saying you can close the app completely and as long as notification is turned on the call will still come through. See question 1 above to see if I've got it right about an app running in background and closing an app. I always thought when you were viewing an app and you home clicked one and the screen shuts down the app is closed until recently I heard it's not close until you double click and delete it from the bottom under the dock.  I just want to make sure I've got it straight!
