I installed skype on xoom and it will never login to my account. I have the wifi version and when I try to login I get mesage can't login invalid password try again. I have no problem logging in on my desktop or my IPod.
running it on mine right now, i had trouble logging in initially. I would enter my username/pass and it would just hang at signing in. I hit the back button and tried again and it worked. no problems since.
