Version 2.0 of Yeigo has just launched according to the South African developer. Yeigo is a new mobile app that uses a handset’s Internet connection to make calls and send SMS or other instant messages. Best of all many of these options are free, such as calls to other people using Yeigo. Calls to non-Yeigo users can be as much as 80% less as well. Yeigo will also lets users send free IM via GoogleTalk, MSN, Yahoo!, AIM, ICQ and Jabber. This service will work with domestic and international calls.

I can’t run it on my phone, but have been receiving phone calls from Yeigo users and the quality is great! Apparently it only uses about 5 MB per hour talktime, as opposed to Skype using about 30MB!
