I always used to think Sprint & Verizon were similar style carriers.. then AT&T & T-Mobile were as well.. so those were the respective carriers one another could be unlocked for..
Maybe that was never the case.. but now I find the whole unlocking thing confusing.. thought it used to be CDMA stays on CDMA .. GSM stays on GSM..
