I'm curious about the upcoming skype app. I current have a skype-to-go number - along with unlimited world subscription (that soons expires and will be renewed) and a skype number.

From either my BB or my iPhone, I can call this skype-to-go number and then either hit speedials 1-9 or dial a number (domestic or international) and pay regular skype rates (or free if included in my unlimited world subscrip).

Now this will only work with network access, in my case, TMO. It won't work on only wifi - for that I just downloaded Nimbuzz.

When skype app opens up tomorrow, it will only work on wifi and not carrier network. Does that make it better than my skype-to-go method? I can see it better for iTouch owners but normal iPhone users - any real difference?
