swipe back is a tweak released during this evening in Cydia, and with its help you can use gestures to return to previous application menus. After installing the tweak from Cydia, you can swipe from left to right and vice versa to return to the previous menu of an application or to return to a previous web page. The tweak has a settings menu in the Settings application of iOS, there you can specify the applications in which it is active and that's about it.
SwipeBack is available for free in Cydia's BigBoss repo.
