I want to send a sound file to an iphone user and did the following test
1. Recorded a short audio file on the Droid using the Voice recorder app
2. Emailed the file via gmail to myself.
3. Played fine on the Droid and played on my PC using Quicktime
4. When I tried to open the file on my ipod touch I heard no audio when quicktime played it.
I assume its some conversion program I need.
