This is going to be a great holiday gift for many of our readers. Tango Video Calls, the app that lets you do free video chats with friends over 3G as well as Wi-Fi, has been updated to work on the 4th generation iPod touch. Rather than use the app for registration, you can register via email.
The update, which also applies to the iPhone 4, gives the contact list a new look and feel and also has improved resolution on the Retina Display.
Check our previous review for details on how Tango works, and if you have a newer iPod touch, well, get over to the App Store.
