I've posted about Republic a couple of times before, here, here, & here.
Starting soon, they will be offering the Moto X as their flagship phone with some great tiers available on their service. Since they operate as an MVNO, they utilize the Sprint network for their service. The kicker is they can offer these VERY CHEAP plans because the phones are set up do do most of the communications via WiFi and only use a cellular connection when no WiFi network is available.
Anyway, they are doing a giveaway for a "Moto X Prize Pack with 12 months of 3G cell service and tons of accessories!" You can enter at the link below.
*****Disclosure: By utilizing this link, it gives me more chances to win a prize pack.*****
