Ringtone Styler lets you enter a ringtone in the popular RTTTL format and converts it to midi to be used as a ringtone.
Additonaly you can:
* choose from up to 128 instruments
* change pitch
* change playback speed
It's available from the shop:
http://www.handango.com/ampp/store/PlatformProductDetail.jsp?siteId=308&productId=143594
A free demoversion is also available. It runs for three days and the instrument used when saved as a ringtone is always a piano.
This is a MIDP2.0 application developed for and tested on the 6600 but should work on other MIDP2.0 enabled Symbian phones.
Free ringtones in RTTTL can be found using google.
Kind regards
