[network world] Several chinks are appearing in the way we've historically separated voice from data, 3G from traditional cellular, and international calling from domestic calling. With many businesses and individuals fixated on cost savings, some industry developments have cropped up to help avoid or at least reduce international roaming fees.
For example, as of last week, Google Voice is now officially an iPhone app at the Apple App Store and is also available for the Palm Pre. Outbound calls use the AT&T voice network to connect the call but route it through Google Voice. So the Google Voice phone number is the source calling number, which should avoid afford the opportunity to avoid international long-distance charges.
