Facebook++ 開發者發出的訊息：
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!
