TweakDoor:
 TweakDoor is one of the latest unofficial app installers. It offers 
users a fantastic choice of third-party games, apps, tweaks, 
emulators, and more of them with extra functions and features. 
Although there are tweaks, don’t expect them to work the same 
as they do when run with a jailbreak. You will get some benefit 
but not as much as you would using Cydia.
