Hi, I have a mic from Nokia (like the Philips iPhone Microphone Adapter). Well, I use the app Fring. And I do some calls (using voipstunt). But the mic doesn't work correctly in the ipod. For example, when I call to a phone with the ipod, I can talk from the phone and I listen all things that i say in the ipod. But when I talk from the ipod with the mic, in the phone I don't listen anything (but when i'm talking, I listen to me 5 seconds later in the ipod (so the mic is working, but in the phone there's no voice). The nokia mic has got a button, and I prove to push when I talk, don't push, etc. but there's no way. Any suggestions?
