Skype Software has launched a major update to its popular Skype application for the iPhone and iPod touch, introducing the ability for users to place VoIP calls over the cellular 3G network. Although Skype-to-Skype calls over Wi-Fi will remain free, Skype has indicated plans to charge a “small monthly fee” for placing Skype-to-Skype calls over the 3G network, suggesting that 3G calling will be based on a subscription service, rather than the per-minute system currently in place for Skype-to-phone calls. These fees would be in addition to data charges already levied by the user’s carrier. Skype plans to introduce this new fee structure in 2011, and will be providing free 3G Skype-to-Skype calling until that time. The new version also implements a new codec providing “near CD-quality sound” for Skype-to-Skype calls on iPhone 3GS, iPad and second- and third-generation iPod touch devices. Other improvements include an enhanced call quality indicator, improved start-up time, and faster access to the dial pad from the iPhone home screen. Skype is available from the App Store as a free download.
