Hi bout a 9780 a 2 weeks ago from Amazon, but it turns out i bought the wrong frequency ( t mobile version) was so excited i didnt check for the frequency ,so i wont be able to get 3g.since i live in the caribbean returning it is not an option. i bought it for 400us but can only get it sold for 325us although its a new phone. is 3g worth it or should i sell it take my loss and buy a new one or a 9900 with the correct frequency.
