That is a myth. I just read the other day that RIM had created their own Skype app that worked quite nicely. However, it was killed by the voice carriers, ATT, Verizon, etc.
To see that VOIP works on the mobile platform and 3g, check out RIM's own VOIP system, that I think runs on a BES.
To assist in the question about making cheap international calls, you don't need Skype anymore. You can make calls to about 35 countries, and growing, for the price of a local call. Just go to
hxxp wwwDOTtalkster.com on your desktop
hxxp freeDOTtalkster.com on your phone
This is the company that powers Google Talk and there are no catches other than you have to enter in the specific phone number you'll be calling from and to, landline or mobile is ok. Do this once and you're set for life.
Call Europe, China, etc. for just regular airtime.
Hope this helps.
