According to Mel Martin of TUAW:
According to the fine print on the Skype iPhone app, free Skype to Skype calls will last all the way until the end of 2010. Yesterday, the date was given as the end of August, but it looks like we’ve all gotten an extension on Skype-to-Skype calling over 3G.
It would appear the outcrying from users has worked to some extent, insofar as the institution of charging has been delayed by about six months. No explanation was offered, but it is not unreasonable to assume this was in response to the many complaints.
I still have to question the need for instituting charges for Skype-to-Skype calls via the 3G network. While Skype does need to make money, every other Skype-to-Skype call is free. Why penalize iPhone users unless the idea is to capitalize on the perception that iPhone users have no problem spending cash?
