Hi New here. Be gentle with me. I've just got a Desire on O2 (it's lovely) but I'm having problems getting my own mp3 files to be ringtones. I've followed all of the different instructions on here about which folders to store them in but it just won't work! If I browse to one of the files with Astro and long press on the file, a menu appears. Under Music Options, the Play and Set As Ringtone functions are not available. The files are currently on the SD card under \media\audio\ringtones. I have tried setting the files as ringtones under the Personalise option as well as the Notifications and Phone Ringtone options. Thanks in desperation! maccboy.
