Yep.. that error is telling you that it can't write the ring tone you
wanted because it's not w/in the proper parameters. For example, MIDI
type 0 is a type of ring tone.

You have to make sure that each ring tone is in the supported type. I
think the 730 is the same as the 830 as far as ring tones... it should
support WAV, MP3 and MIDI types.
