Has anyone tried Skype for Blackberry? Does it actually work and would it save on roaming charges? I'm thinking this might add to costs. Most cell providers cap the monthly data transfer so I can see that using skype on a BB would rapidly increase the monthly data used and in the end you'd be hit with a big fat bill.

Found other useful things on handango.com but I'm not sure about the skype thingy.
