YB app on iPhone

Breaking Bad fans will be happy to hear that Aaron Paul, the scruffy actor that played Jesse Pinkman on the hit AMC show, has helped release a new Yo-style app with a predictable (but hilarious) spin. YB offers a variety of single-direction messages, such as "cool", "later", and of course "yo", followed by his signature line, "b*tch."

Every message includes a sound byte of Paul delivering the line, and has the option to reply to the originating YBer. New messages are unlocked through in-app purchases, and interactive notifications help you send replies easily enough. There are even contests to unlock new phrase packs.
