We previously brought your attention to Tango, a service that allowed users to make free video calls with friends over a 3G or Wi-Fi connection on devices such as the iPhone or Android devices. If you happen to own a 4th generation iPod touch and have been jealous over your iPhone friends, the good news is that the app has been updated to work on said iPod. Aside from the iPod support, the updated app also gives the contact list a new look and feel and also improved the resolution on the Retina Display. You can check out our previous report on Tango to read the full details of it.
