PrimeTime2Go brings full-length TV episodes to BlackBerry Bold, Curve 8900

Ah, so the rumors were true. As BlackBerry App World descends upon the masses today, a particularly unique service is launching alongside of it: QuickPlay Media's PrimeTime2Go. Unlike options from Sprint and AT&T, this alternative delivers video only over WiFi, though this arrangement does enable it to work on all carriers. The app will bring full-length television shows to certain BlackBerry smartphones, and with deals inked with NBC, CBS and MTV, we'd say the selection should be pretty good. As for details, it'll run users $7.99 per month, though it will only operate (initially, at least) on the BlackBerry Bold and Curve 8900, sold by AT&T and T-Mobile, respectively. So, is this the break that mobile TV has been waiting for? Or is this yet another option that better get used to being shunned?
