I have an AT&T Palm Centro and I used Minitones to get MP3 ringtones off my SD card and into my ringtone menu. I can set call ringtones fine, but I am unable to change them for messaging. If I have the sound on and I try to set it, the second the ringtone plays in the messaging menu, the phone will freeze and I have to take the battery out to reset it. My friend had a Centro and used a ringtone for the messaging alert without a problem. Any idea how I can change this?
