i have a curve with a 2 gig card, i hooked it up to my mac with the mass storage mode and dragged over a couple mp3's as ring tones, they all showed up and worked fine but for a couple there duplicate files placed in there that wont delete out. so if i put an mp3 named song.mp3 there would also be a file named ._song.mp3 showing up on my blackberry, even if i delete song.mp3 the ._song.mp3 file doesnt go away. can someone help me out?
