Alright, like every other new guy on here, I'll proclaim the disclaimer of, "This may be a stupid question"
Just updated my tilt to 6.1. (I don't know why now, but that's a different story)
I've now noticed some MP3s aren't showing up in my available ringtones list anymore. They seem to be the bigger ones. At least a couple MBs. After I updated and restored my phone, my ring tones I had set for certain people stayed the way they were. Unfortunately I got a bug up my but to change some stuff around and changed one of my contacts ringtones. When I decided I'd better leave it the way it was, it was too late. I couldn't go back to the previous tone because it wasn't available to choose. The files still exist in the same spot they did when they were available and are still playable on the windows media player. Any clue to what's going on here, or am I just missing something painfully obvious?
