I have skype app on a 3G 3.0 iphone. I tried the cydia app voIPover3G to get it working when not in WIFI. Didn't work, so I just purchased 3G unrestrictor. I uninstalled voIPover3G. I then turned the iPhone totally off and then added skype to 3G unrestrictor. I still continue to get the error message when I dial a number from skype, "You're offline. You need to be online to make a call." I press call anyway and it doesn't work. I turned WIFI off to test it and also left it on without a WIFI network picked. I am on T-Mobile pay as you go if that matters. But 3G unrestrictor does say it works on Edge so don't think that should matter... Any other tricks anyone knows to get this thing to work?
