Can anyone suggest the best international calling apps and if these apps use data, approximately how much data they use? I am looking to find a blackberry app that has free international calling over wifi/3g services for my Blackberry Bold 9930. A google search rendered some apps such as tringme but I wanted to post here to see if anyone had opinions on which apps worked best. I have verizon if that makes any difference. The help is very much appreciated. Thanks.
