Video calls using 3G technology has been around for quite some time already, but we rarely see people use that, as most folks seem to rely on voice-to-voice communications more. Perhaps it is because you need to hold up the phone and talk using a Bluetooth headset to maintain the privacy of your conversation, or it could be due to the slightly higher cost per call – whatever the case is, it has failed to take off in a big way. Well, we suppose if it were to be free, then the adoption rate might see an increase. Yahoo! decided to throw in video chatting capability into Android-powered smartphones, so make sure you get one that has a front-facing camera otherwise it would feel as though you were speaking to a wall, with the back of the phone facing you. The new version of Yahoo! Messenger for Android will require Android 2.2 at the very least, so do take note of that.
