A friend of mine is asking me of the cheapest method to get a Nexus S. First, let me explain the back story, my friend renewed his contract with around 1-2 month ago and he got a G2 for it. It is already past the grace period for return headset(I think it is within 30 days) so he would be stuck with G2 unless he get Nexus S without contract. He said he is having some problem with the phone and he plan on call up the warranty to get a new one. He is considering selling the new one he got from exchange and use the money to buy a nexus s without contract. Is there a better method?
