Guyz forget skype or any other video chatting app coz we got IMO now.
This is the best app ever to do video chat or phone call. Commonly know skype messgner gives you option for a video call but it hardely connects.
But imo is superb even if you are using it on 2g speed it will work fine , oh wait not fine its awsome and phone calls dont have any disturbance. If you are having 3g data or a wifi then you will gonna experience an awsome video chat. Try this and you will forget everything else.
