We all know by now that we can't use 3g on T-Mobile or can we? What if I were to take a 1700 MHz receiver and place it into a case like some do with backup batteries then connect it to my iPhone? All I would have to do is softmod it so it use the external receiver instead of the inernal one giving us 3g. I know that is way harder then it sounds, but it is still posible. Please give feedback on this idea and I might try it.
