Republic Wireless' low-cost, WiFi-driven phone service has proven tempting. The rapidly aging smartphones attached to that service, however? Not so much. The carrier will soon improve that device selection, as it has just revealed plans to sell the Moto X for $299 off-contract -- roughly half of what it costs at other providers. Service is also expanding beyond the original $19 plan (now limited to the Defy XT), with steep discounts if you don't depend on cellular service. Rely solely on WiFi, and you'll pay just $5 per month for unlimited access; a $10 plan will be available if you need cellular voice and text messaging. There will also be more traditional plans with unlimited 3G and 4G data that respectively cost $25 and $40 per month. Republic Wireless hasn't said when its extra-cheap Moto X will be available, but the new rates should take effect in November.
