As we close in on the established November timeframe for the BlackBerry 8130 from Sprint, the leaks start coming in like bad plumbing. Not only have some docs confirmed a 23rd. release date for an amethyst Pearl, but there’s also word of some new BlackBerry plans, including an unlimited-data-and -SMS BIS deal for $30. That sucker also includes unlimited Navigator use on that shiny new BlackBerry 8130. Fine time to to switch to Sprint, eh?
