The Samsung Gravity 3 from T-Mobile has a price of only $49.99 USD when purchased with a full two-year T-Mobile contract. In this case, since T-Mobile is probably the only retailer for the Samsung Gravity 3, unlocking may not be cheap. Even if you did switch carriers you would have to pay at least $200 USD penalty for cancelling early. But the Gravity 3 is still a GSM phone as stated in our previous review and as such will be unlock able. Stay tuned as we learn more about the price of this smartphone in other countries like India.
