it's a good idea to put them in the device memory instead of on the sd card. that way if you change sd cards or have the phone plugged in and the phone is in mass storage mode,you will still have your ringtones. i did this a while back and when i just recently deleted my ringtones out of the app memory via bbfilescout i didn't notice any increased memory.
on a side note...if anyone wants other ringtones like iphone,nokia,nextel, aol or yahoo let me know. i have those as well.
Hey I'd like sum of those other tones PM me. Posted via mobile device
