NBA Jam has always been a favorite of hip-hop and sports game heads, but it’s about to get even bigger now that the title is coming to the iPhone. EA announced the move last week, and today the gameplay trailer officially landed. The app will feature top ballers from 30 NBA teams. No word on how true to the arcade original (or last year's reincarnation) the title will be; we can only hope that there are some good secret characters—and big heads (II)—in the mix.
