I have had my 7100i for about a month now and I have searched high and low for the nextel ringer 10 for DC Alert in the midi format. It is not out there! Attached is my version for anyone else that misses their old tone. It is not 100% but it is much better than the choices on the phone.
Enjoy!
Obviously can't attach a midi file.....link attached
