I was charging my phone last night, unplugged it and it basically told me my memory card is missing. I read that most of them can become corrupted, so I replaced it, with the same thing: a 16gb Micro SD... Still doesn't read my card!! I can't take pictures, I can't have music, etc..... When I plug it in to the computer it doesn't read it either. Nothing works. I took it out, put it back in~nothing! Do you think there is something wrong with my phone? I might just have to take it into my local store, huh? Grrr..... Oh and I "factory Reset" my phone, too~still won't read my cards!
