How does skype work on the iPhone? I got a 3g and i want to make calls overseas, i can use wi-fi, i rather use 3g if it will work. The main question i have is do i have to make "skype to skype" calls or can i call any regular mobile number? Thanks for the help. I suppose i have to use "Fring" as there isn't a certain Skype app right? Please help.
