Hey. I wanted to know if there is an app that lets users call others on Skype to Skype. I heard of Fring, but I think it can only be used for SkypeOut to landline or cell phone. So, can you call from iPhone 3G to computer or vice versa? Because on the computer, it's free, so it should be on the iPhone if it is made. Would it work over 3G/EDGE cause of the SDK restrictions? Thanks in advance!
