Voice over IP service Skype announced this morning that it has launched on the Apple iOS operating system, supporting Apple's iPhone, iPad, and iPod Touch. The app--formerly known as Skype Access--helps connect Skype users with Wi-Fi hotspots around the world. The app is free, and allows Skype users to pay for as many minutes of Wi-Fi access as they want. Skype is targeting the new app at both recreational and business travelers.
