Multifl0w has been a tweak on Cydia and with the Jailbreaking community for a bit now. It recently got an update and looks great. You have a ton of customization that allows you to choose how you want Multifl0w to pop up. Whether its swiping the status bar down or any other of the numerous features it offer, Multifl0w should have you set up perfectly. The UI in Multifl0w will twerl your open apps onto the screen with a screenshot of where you last left it. This is how Apple should implement multitasking, but I can't complain with their method now.
