At 1 time I had an HTC Evo 4G and a EVO 3D on the same line. I sold the 3D a while back and completely forgot about the 4G. I want to do something with the EVO 4G but I have always heard you can't have both phones on at the same time. I don't want to mess up the guy that bought the 3D and I have no way of contacting him so my question is there a way I can reset the phone back to Sprint? Would a hard reset do this or maybe Ruu?
