If you've got a Sony PSP Slim & Lite and have been waiting since CES for a system software update so you could make Skype calls, now is the time to act. All you need to do is to upgrade your handheld's system software to version 3.90.
With the update, foreshadowed in Sony's PlayStation blog and now also announced by the Sony folks in Europe, PSP Slim & Lite users can make free voice calls to 276m other registered Skype users, see which friends are online and available to talk.
Also, if you have a bit of Skype credit lying around, you can use your PSP to make cheap SkypeOut calls to landlines and mobiles anywhere on the home planet.
