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.
