I recently installed the Skype app on my iPhone. It works well at home on any WIFI connection, but I wanted to put it to the test out of the US. On a recent trip to Mexico I was able to use the free WIFI at the Starbucks in Playa del Carmen Mexico. The service worked without any glitches, and because I was calling US numbers from a US phone the rate was .02 per minute to call landlines versus the .80 per minute ATT Mexico rate. Looking forward to making iPhone Skype calls in Europe. The connection was impressive considering I was an hour from any major metro area in Mexico.
