This is a program that will let you take MP3s and WAV files and turn them into
ADPCM formated files for playing on the 7100.
However, if you have the 7100i you are out of luck....
I bought the program before I noticed this.
So now I am going to call Nextel Blackberry Support and do some serious *****ing. What we need is somebody who has a 7100r or 7100t to show us what service books they have for their phone. I believe if we can get the service book for that feature, we can do it with no problem.
It is total BS that the 7100i does not support this. Every other 7100 does, so it is Nextel. Not RIM.
Hope this helps.
