I saw a Skype app, I think on Handango.com, for free. Thought I might try it -- but you say it won't work? (No big deal for me either way, but it would be nice.)
I just checked: The Skype website shows an Android dowload that requires 2.1 or higher. It also lists a Linux version that requires a 1 GHz processor (I'm not real clear on what the underlying Linux does for the Edge). So neither of those will work. I went back to Handango, and the Skype they list supposedly works on Android 1.6 or later. Dunno if it's true . . . . I probably won't test it myself.
