My friend who is not very tech savy rooted his captivate using one click method. He called me today and said that he has lost all 3g and edge connections. I own a DX and am not very familiar with att and captivate. I would not think that rooting by itself would do this. I have never ran into this issue. Any help would make him feel a whole lot better. He is on a road trip so he is pretty stressed.
