I'm considering getting an iPhone 4 and leaving my Blackberry. I currently have the first generation iPod Touch. My question is about multitasking/app switching. Let's say I'm in an app such as Tap Tap Revolution. On the original Touch/iPhone if you press the home button (once) in the middle of the game you are brought to the home screen and the game quits. When you go back into the game, it boots up from the beginning and you are not where you left off. Is this the same on iOS 4? Or is it set up so that when you press the home button (once) the game pauses in the background and you are sent to the home screen and then when you return to the game it is where you left off? I'm talking about single tap of the home button, not double. Sorry if that was confusing.
