One of the best Cydia apps you must download is MxTube. MxTube allows you to view and download YouTube videos straight to your device and view your videos there. Its a really neat application. The only problem is that they really need to make a feature that enables you to sync those videos into your iTunes library. You can only view the videos you downloaded in MxTube. But other than that, it’s a great application!
To download MxTube, in Cydia just simply go to search and type in “MxTube” (no quotes.)
