I am using the philips iphone adapter (http://www.target.com/Philips-iPhon...=UTF8&index=target&rh=k:iphone adapter&page=1) on my ipod touch 2g.. It works great as a recording device, however, I have mixed experience when using it on voip apps (fring/nimbuzz/truphone). Most of time, i start making a call, I will only hear my own voice/noise through it and no call can be made, and after i hang up and try again for three or four times, it will work. It will mute the music if I am listening, but i will still hear the noise for the first few times. 
Is this a well know bug or something about this adapter? any solution? Thanks
