My phone sees my SD card but when I put music on it, it does not see it. When I first transferred music via the USB cord, it worked. I then accidentally erased everything on it! Now, it does not work PERIOD. I tried using the USB cord again, nothing. I tried using Bluetooth, does not sync for music. I then used my SD card in my laptop and put the music on that way, nothing. Anybody have any freakin' idea what the heck is going on? Please help!
