Microphone and voip issue: low volume

Alright, so I was reading all over about getting your Ipod touch hooked up to make phone calls through voip, which is thus far successful, but my only problem is, my mic is at a wildly low volume. I have to yell for people to even make out what I'm saying.
At first I thought this was some kind of built in fail-safe for the Ipod touch that apple put in, but then I tried using a recording program "iTalk" and it records at crystal clear regular volume.
I've tried using Skype through Fring but now i'm using Truphone.

The only issue I'm having here is the input volume on voip calls only.

My ipod is the newest model, I just got it yesterday. I'm fairly new to the Ipod touch, Iphone scene so any help would be appreciated.

Specs for knowledge purposes:
Ipod touch (2nd gen?) 8gb
the microphone is a: Xtrememac Micromemo. It was originally for my Ipod Classic, but it works for the touch as well. I rigged up some headphones when i took it apart for my sound output instead of using its built in speaker. (when plugged in it covers the normal Hphone jack and doesn't allow ipod touch speaker use).

The Microphone on it is removable to reveal a line in jack, I could potentially hook up a preamp to boost the volume on pre, but that would ruin is size and make it not logically mobile.
