As you know iPhone 4’s FaceTime can only work over WiFi network. While iPhone hackers figure a way that lets user to use FaceTime over 3G, you need to have a jailbroken iPhone 4 in order to make it work.
A startup called Tango targets to bring free video calling over 3G to iPhone users without the need of jailbreaking. On Thursday, the company released an iPhone app called Tango Video Calls. It’s just like FaceTime that lets users to make video calls between each other.
Supports iPhone-to-iPhone, iPhone-to-Android and Android-to-Android Video Calls
However, unlike FaceTime that only works over WiFi and between people with iPhone 4 (or the latest generation of iPod touch), Tango allows you to make free video calls over cellular network. You can even do a video call with friends using Android phones. It’s cross-platform. As long as both users are installed with the Tango app, they can make video calls with each other.
So far from my test, the app works as advertised. The video quality is good though not on par with that of FaceTime. When you first use Tango, it automatically imports the contacts from your iPhone’s contact list. The app then scans through the contacts and show up only those with Tango installed so you can make video call with them.
Like FaceTime, Tango utilizes both front and rear camera of iPhone 4. It’s very simple and easy to switch between these cameras. Just tap the swap button to switch to the back camera and show your friend what’s around you. Tap the same button again to switch back. During a video call, for any reason, you can simply tap a button to switch back to audio call.
Make Video Call using iPhone 3GS
Tango even supports video calling on iPhone 3GS, which only equips with a rear camera. Without the front-facing camera, you can’t have a face-to-face chat with friends. But you can show your friend what’s around you during the audio call.
Overall, Tango is a great app for iPhone 3GS and iPhone 4 users. And, this is how Apple should implement FaceTime. If you subscribe to an unlimited data plan and are frustrated with the limitation of FaceTime, Tango will definitely fulfill your need. Not to say, you can make video calls with friends using Andriod phone.
Tango is now available on App Store [iTunes link] and it’s free. Go ahead and download it!
