It was only yesterday when we reported the long awaited update to install0us (version 2.5) and now it seems like the developer of the app has already pushed a new update, version 2.5.1 via Cydia. The only thing new in this update is that it removes the expiry date that the developer forgot to remove from version 2.5. Version 2.5 of the app will be expired in 4 days from now. You must upgrade to version 2.5.1 in order to continue using this app. Here are the official words from the developer himself.
