One of our favorite cydia apps has been updated for the iOS 7 jailbreak. VideoPane is an amazing work of art when it comes to using the iOS 7 jailbreak to its full potential.
If you have ever wanted to watch a video in another app or screen, this is for you. It is basically a PiP cydia app that works with the current iOS 7 jailbreak. There are endless uses for this app. One way we typically use it here at AllCydia is when browsing a safari tab you can watch a video right on the same screen rather than booting another app.
The price tag on this is $1.99, but it is well worth the money if you get frustrated having to go fullscreen to watch a video.
After you download cydia for iOS 7, you can boot up the cydia app and do a quick search for VideoPane. So download this cydia app and enjoy the freedom of PiP!
