Skype has launched a beta version of a mobile thin client, available here. The application is available worldwide and includes chat, group chat, presence (seeing when your contacts are online), and receiving calls from Skype users, and through SkypeIn. Skype-to-Skype and SkypeOut calls are only available in Rio de Janeiro, Denmark, Estonia, Finland, Poland, Sweden and the UK. An unlimited data plan is recommended—although the service works over standard mobile voice networks connections for the first and/or last legs of Skype, SkypeOut and SkypeIn calls—and over the internet for the rest. Presumably you’ll be paying standard carrier rates for the voice calls, but it should be a local mobile call rather than an international one. (release)
