You can head over to the Market and get a new updated version of Skype. The v18.104.22.1683 version fixes a security vulnerability that would have exposed personal info to hackers. The leaked video version of Skype still has the vulnerability, so be wary. The new update also adds an interesting new feature. Skype can now give you the option to use it for 3G calling. That's pretty slick!
