Can make MP3's, midi, wave and such. Bascially set the song timer to play only what you want as a ring. Only problem is the sound quality must be adjusted to a very low setting. Another thing with i860 is that it will only play 4 seconds of the song, pause for a few seconds then play the remainder. I'm having the same issues. Works fine for my i730 but not with the i860. Guess Nextel is making it more difficult to download rings.
Forget all about webjal. it sucks. Try myJAL. It's free to use for 10 days, then you have to register for $10. it's well worth it. Apollo Edition supports i860 and all phones below that. It also supports MP3 uploads for i860's. Check out: http://members.cox.net/myteam/
