Verizon is about to drop the prices on the Kin One and Two in a sign that Microsoft's phones might not be selling, sources said on Thursday. Although only launched last month, the Kin Two would drop from $100 to $50 on contract; the Kin One would be even cheaper, falling from $50 to free with a two-year plan. Both cuts would take effect on Friday, but BGR notes they wouldn't change the smartphone-level plans required for either model.
