I’m a fan of FaceTime… I travel so it has been a life saver to keep sane through seeing the face’s of family members when we talk online. Using either my iPhone or iPad, I can ring up family members and if they are on a WiFi network they answer and we chat.

There is a small limitation with FaceTime, it only works when both ends of the call are on devices connected to the Internet via WiFi. For those times I want to ‘video’ call iPhone to iPhone over the cell network, I have been turning to Tango. Like FaceTime, it’s a free app and it’s free to use.

Along with the 3G connection ability, there are other differences between FaceTime and Tango Video –

Start the call with audio, once connected you can switch to video.

If the person your calling doesn’t answer, you can leave a video message (in-app purchase 5 for 99 cents).

No login/password required.

Friends can be found through the Tango people search.

There are some kind of animations you can add… but I have never played with them.

Works on iPhone 4S, iPhone 4, iPhone 3GS, iPod touch 4th-generation, iPad 2 (not the iPhone 3G)

Connects to more than just iOS devices – Windows Phone 7 and Android phones and tablets (3G and WiFi)
