Hello, I just found out about Sip-VoIP on the iTouch. So I really wanted to be able to actually recieve calls from my iTouch. So I searched "free VoIP-in number" on the internet, and I found ipkalls.com. I registered at FreeWorldDial-up and then at ipkalls and got a free phone number! And I was able to call my computer from my cell phone! But I have no idea what to do to get it working on my iTouch. Can someone help me?
