PhySwitch Cydia Tweak - Alternative App Navigation
PhySwitch is a Cydia Tweak which replaces the iOS multitask bar, you can now switch between different apps (opened) using any of the activator options. A nice looking navigation screen pops on top of your current view and using the up/down volume buttons you can navigate through the different apps or you can simply swipe through the list of apps.
Another tweak down in the app navigation records
