Skype on Fring works on iTouch. Download Fring from iTunes App store, under "social networking" apps. Free app. No jailbreaking required. Works on G1 and G2 Touch. All you need for G1 is a microphone that connects through the doc. Touchmods seesm to be the most readily available and reliable. There is a "Sykpe OUt" button and a dial pad to make calls. I have called several numbers on my contact list and connected and heard people speaking. If anyone could test this app with a microphone and confirm that you can speak and be heard on on the other end, I would appreciate it, as I do not have a microphone yet.
