Hello. I have an X10a from Rogers, rooted yesterday...Titanium backup, busy box, astro, and explorer installed. I applied some fonts yesterday so I know I have the root done right but i'm having trouble figuring out sounds. I would like to take an mp3 i have and put it in my notifications for email/texts but when I try to copy it to \system\media\sound\notifications it says I cannot paste. How can I do this? Do notifications have to be .ogg files? Thanks!
