CNet is reporting (read, passing along a rumor) that Skype is coming to the iPhone and iPod Touch -- possibly as early as next week. As you likely know, Skype is the most popular application for making free computer-to-computer calls. It also offers very low cost calling plans to regular phones. And it has great instant messaging and file-transfer features. Of course it would primarily be useful via Wi-Fi, including letting you use your iPod Touch to make calls.
