When you press the command + tab keys on a mac in unison, youll be presented with the app switcher equivalent of Mac OS X. CMDtab tweak attempts to bring that experience to your iDevice. It does it well, however I would have preferred it if it was actually implemented as an app switcher, and not as a launcher. However the user interface and animations are smooth, and it actually packs some pretty decent functionality.

CMDtab is available from the ModMyi Repo for free.
