Facebook++ 开发者发出的讯息: We’ve been informed by the BigBoss Repo Maintainer that we are not allowed to have the automatic downgrade feature as part of the tweak. As such, the most recent update to Facebook ++ WILL NOT have the automatic download. Instead, it WILL still have the in app messaging via webview, and it will prompt you to add our beta repo (beta.unlimapps.com) if you’d like to easily downgrade. The steps to do this are: Open up Cydia, make sure you’re on the “Sources” Tab Select “Edit” at the top right, THEN “Add” at the top left in the window put in “ beta.unlimapps.com” and select “Add Source” Update Facebook ++ from the source you just added!
