This is my first post here so be kind- lol I just put ios4.0 on my 3GS and I notice when I hit home button once- I leave the app and goto the home screen like before. Now when I double tap home screen- It shows me the apps that I've run and to close them I can hold them until an x comes up- then I can close them 1 at a time. Is there a faster way to close the App? I would prefer to close the app down the first time when hitting the home button like before. I hate having everything running in the background. Yea 1 or 2 things is good but not everything I have touched! So I know people want multitasking- but how can I turn it off or prevent the apps from doing it? Otherwise love the os- the phone is so much faster doing everything- especially taking a photo is lightning fast!
