As we revealed
this morning, the BlackBerry Curve 8530
-- a CDMA remix of the 8520
now available on T-Mobile -- is coming to Sprint to do battle with its Verizon-branded cousin. Unlike Verizon, which promises a November 20 launch for $99.99 on contract after rebate, Sprint isn't revealing pricing or availability details for the low-end BlackBerry -- but naturally, if they're smart, the answers will be "cheap" and "soon," respectively.
