My 3GS works fine on the Edge network. When I enable 3G, the cell signal drops to nothing for a about ten seconds and then it comes back to almost normal strength. The Edge network symbol disappears and there is no 3G to replace it. When I try and access the data network (not wifi) I get the "you are not connected to the internet" message. If I turn off the Enable 3G nothing happens, I do not get the Edge symbol back. Only way to fix this is to restart the iPhone and make sure 3G is not enabled. I am currently in Saudi Arabia and the phone worked fine in the States. Others out here are running 3G with no problem so I'm not sure what I'm doing wrong.... I am thoroughly stumped. Any help would be greatly appreciated.
