There is a new jailbreak tweak in beta called app admin by UnlimApps which allows users to easily downgrade their apps to earlier versions.
With app admin users will have the ability to go far back to earlier versions of an app by providing the version number of the app you wish to downgrade.
Users can obtain the version number they wish to downgrade via the app’s iTunesMetadata.plist in /private/var/mobile/Containers/Bundle/Application/.
Additional features like auto-update blocking, and URL schemes so that developers can point to specific versions of apps for tweaks that require older versions will be added later by UnlimApps says that he will add.
