Just looking for clarification on using skype from my mobile. What are the cost included? I assume it will just be my data costs on xt and the usage of funds from my skype account?

Paying $1 for 10MB happily funs skype and msn all day, normally wont go over 2mb. Then i can make a call for few cents all around the world for only a few cents... Does it really work like this? Ill be testing it out later to see what happens
