I'm a huge fan of Alfred for OS X. Alfred is a productivity app for the Mac that allows you to launch apps, search, and do a whole host of other things via its sprawling settings. One of my favorite Alfred features is the pasteboard manager. It's basically a place where you can go back and access anything you've copied to your pasteboard.
Understandably, iOS doesn't have anything like this built in, but a new jailbreak tweak allows you to have quick access to your pasteboard from virtually any app as well. The tweak is called PasteboardKey, and it's accessed via the language button on the iOS keyboard. Have a look inside for our full video walkthrough...
