You can now receive Skype on your iPhone/touch, and Blackberry owners can look forward to the service in May. COO Scott Durchslag claims that it has been the #1 request from its current customers. More than 400 million already use the service with their PC, so that is a pretty good target area. One of its pluses is that subscribers can use the phone numbers in their existing iPhone address book. There is no charge for the download and calls between Skype users are free.
