A presentation given by Sony in Sao Paulo, Brazil seems to indicate that the PlayStation Vita will support Skype. And its a good think since even the original PSP supports Skype – it would be a shame for the PS Vita to drop this functionality. The image below shows the Skype logo on the top right of the screen.
Skype can only be installed on the second-generation PSP (PSP-2000), and requires firmware 1.90, a Memory Stick Duo with 10MB free space and a Wi-Fi connection with Internet Access. Due to memory limitation in the first-generation PSPs (PSP-1000), Skype cannot be installed on these models. You can use your existing Skype account with the PSP or you can create a new one.
To Start using Skype, go to [Network] > [Skype]. You will need to either enter your existing Skype details or create a new account to use the Skype service. Creating a new account is easy, and can be done by following the on-screen steps. If you create a new account using your PSP, you can use the account on other devices that support Skype.
