Stephanie from Atlantic Records dropped me a line to tell me about the mobile marketing she's doing for Yung Joc, a top-selling US hip-hop artist (no, I hadn't heard of him either, but then I guess I'm the wrong side of 22, much to my chagrin). Stephanie tells me, "to be a hustler, you gotta know how to trade like one. With the rise of the digital age, trading cards are shedding their physical skin and moving to the mobile world, Yung Joc style. Collect, trade, and redeem Yung Joc wallpaper for your cell phone and you could win a grand, or a call from Joc himself. Sign up for Yung Joc trading cards at cards.yungjoc.com or Text JOC to 87233 (TRADE). Get 3 cards straight to your cell for only a $1 a week. Collect all 42 and you just earned yourself street cred and an A in Hustlenomics. Competition is for US residents only.And while we're talking about gaming and gambling, did you know there's new legislation covering this area in the UK. And as legislation is such a minefield, the nice folks at Million 2-1 (the lottery and games company), have created a lovely free guide to the new regulatory framework covered under the directives and legislation laid out in the new Gambling Act (effective September 1, 2007). Well worth a read if you're looking to do anything using premium rate SMS and telephony.
