Finally this is official that you can now make unlimited free Skype to Skype or cheap international video calls (VoIP) on your Play Station Vita gaming console while playing the video games on the Go!
Be comfortable to play video games and do Skype video calls on PS Vita by Sony, make free VoIP calls or low cost long distance calling to regular phone numbers worldwide using WIFI or 3G data plans ... and turn your PS vita into a smart VoIP video phone or a smart cell phone (without a SIM)!
They say: how it works:
"...The Skype app includes free Skype-to-Skype voice calling, as well as high quality video calling that utilizes PS Vita's front and rear cameras. The Skype app on PS Vita runs in "background mode" while you're gaming or using other applications** -- meaning you have the capability to "pause" a game, conduct a call and then return to your previous activity -- so you never miss a call. Plus, with a little Skype credit you can make low-cost calls to landlines and mobile directly from your PS Vita..."
