Did you get a new iPad or iPhone this holiday? If so, Skype has a treat in store for you -- it just updated its iPad and iPhone apps to support two-way HD video chat on all A7-equipped devices. Not that Skype is leaving older hardware without an upgrade, mind you. The same update lets the software receive chat messages in the background, and those messages will sync faster across every gadget you own. Whether or not you live on the cutting edge, you'll definitely want to visit the App Store for the update.
