This year at at CES, Slingmedia was supposed to be unveiling their software running on BlackBerry Pearls. That didn't exactly happen, and I haven't heard boo about it since, so I'm a tad skeptical if this new partnership between TiVo and RIM will come to fruition or fizzle like the rest of the "TV on BlackBerry" initiatives.
Supposedly, although details are limited, BlackBerry Smartphones will get customized TiVo services on them. This will enable cell phone users to watch their scheduled television recordings on the go. Now let's just keep our fingers crossed for this one!
