I'm heading to the UK and Ireland with my Droid. I've got a Google Voice account, I've installed Fring, I also have a Skype account. And I'll have WiFi everywhere I go. How the heck do I make a free intl call with this stuff? I can certainly call a Skype account if the recipient is sitting at their computer. But can I call a phone for free? Or receive calls for free? Thanks for the help. Leaving in 24 hours, I waited too long to figure this stuff out!
