Today I assembled my walmart mic in about 20 mins and installed the voice recording app to my ipod. After making 3 crystal clear recordings, I decided to place a call through the WI-FI. The call was very distorted and had a loud whistling/wheezing background noise. After making 2 more crystal clear recordings straight to the ipod, I concluded there must be some outside interferrence against the WI-FI signal. I figured a cordless phone frequency must be to blame. Taking the battery out of the ancient cordless phone in the kitchen solved the harmonics issue and my call was extremely clear. I still had the 1 sec lag but hey it worked! Hope this may help someone. I think I'm the first person to complete a successful call through an Ipod in Chicago!!
