By now you may have heard the big news eariler this week that Skype released Skype for iPhone which is an iPhone app that enables you to make free Skype-to-Skype calls from any WiFi zone. You can sign in to Skype via 3G, WiFi, GPRS or Edge and see who is online but calls only work on WiFi. iPod Touch equipped with a microphone can also take advantage of the Voice over Internet Protocol (VoIP) calling. You can make free Skype-to-Skype calls and low cost calls to landlines and mobile phones – and participate in conference calls – from any WiFi zone. You can also IM all you want, and participate in group chats too, whenever you have network connectivity, whether it's WiFi, 3G, EDGE or GPRS. The next version of iPhone 3.0 supports calls over 3G as this video demonstrates. Om Malik has been covering Skype on his blog for some time and his review of Skype for iPhone: Awesome. While there are a few issues that many say will be worked out in 3.0, Om says, "For those of you that use Skype on a daily basis and own an iPhone, this could very quickly become the simplest way to make long-distance calls. And I’m predicting a big upsurge in Skype as an “IM client” with this release. To Skype developers who worked on this product, I have two words: Great work!"

In less than two days after its release, Skype for iPhone was downloaded more than one million times – around six downloads every second. I downloaded the app on my iPhone and and easily logged into one of my Skype accounts and was making a VoIP call through my WiFi connection in minutes. All my contacts downloaded and I was able to see their status just I could on the Skype desktop client. I was able to text chat as well (without those fun emoticons) and the only thing really missing was video, which is not supported on the iPhone as of yet. The audio quality was very clear and while the latency of text chat was not real-time it
