Great concept, function leaves a lot to be desired.

Although I can make free calls and receive free calls, the 3G connection is terrible, even the wi-fi connection is terrible. The ad in front of the phone call didnt even bother me but the lack of bandwidth? or whatever, where people on the other end cant hear me well, its a great concept, sucky execution. Stick w/ Skype & Google Voice.
