I haven't owned a Nexus device. Basically google will sell the 4th version of their Nexus phone on their website for 300 dollars (8gb) and 350 (16gb). GSM version.
Problem? No 4G, since there needs to be a contract for that and no CDMA so no Sprint.
FFS! T-Mobile is a retail partner, if you have them.
Just saying, I hope more companies do this. I hate contracts!
