Remember Riz? He was that guy that started his career with a song called “Ping!!! Me baby!” and we think it was popular enough that it landed him a record deal. Having recently checked out his site, it doesn’t look like he’s doing songs about BlackBerry anymore but he does have a line of t-shirts that he’s selling with custom QR codes and his famous “PING!!! ME BABY” written on the shirt. It would be cool if Riz could sell these shirts over BBM, but from what we hear, you can’t sell physical goods with RIM’s in-app purchase APIs.
