I've been working on the "social networking" aspects of Loopi - the ability to save "loopi voice" files to a net repository, tag them, describe them and control their permissions as to who can see them. A lot of that is not done yet, but, another thing I'm working on is saving the audio in various formats. for instance, if you save it as m4a (mp4) with a suffix of m4r,it's a ringtone that can be downloaded from the repository and opened in iTunes, ready to synch to the iPhone.
This example came from the iPhone, not the simulator:
Click and open in iTunes
I'm wondering if m4r's opened in Safari on the phone install themselves as ringtones. I suspect not. That would be too easy!
