I've tried searching through old threads to see if I could figure this out from existing responses, but couldn't quite figure it out.

I am looking to upgrade my BB and am thinking of the 8120 for use on AT&T's network. I don't travel internationally all that often, but when I do would like to be able to use one phone if possible and avoid hotel connection charges to use a calling card. Due to security restrictions, my work-issued laptop isn't able to run Skype or any other VOIP software.

If I have Skype loaded on my BB, and that BB is connected to the internet via a WiFi connection, is it possible to make SkypeOut calls without incurring mobile phone minutes at int'l roaming rates or even int'l roaming data rates?

Thanks for any help anyone can provide!
