n-gage ringtones add?

[kwaka750]

hi, can anyone tell me how to add ringtones to the n-gage without paying for them to be sent? i have bluetooth on my laptop and also the cable that comes with the phone. if you add a midi to the audio folder it will let you set it as a ring tone but does not play it when your phone rings, also worked out that when you record a song from cd etc it saves it as a aac file this can be set as a ring tone and works ok. i have made some aac files from some chart hits but can't find where the n-gage saves the aac files to.
any help or info would be great .... thanks
