I was just reading a great post on BlackBerryForums.com by Sci-Tek where he mentions 3 different SNAKE games that work or may work on BlackBerry devices. I tried the first two and they worked and caused some serious nostalgic reflexes. Just though I would share. Let me know about your experiences. Thanks Sci-Tek!
