In his video interview with Josh Silverman, Skype CEO, Gigaom blogger Om Malik asks: "Where is Skype for the iPhone?"

Silverman's response? "Stay tuned."

He told Malik: ""We need to be on all devices...Skype needs to be everywhere."

Malik: "While (Silverman) wouldn't get into the specifics, he pointed out that, with minimal promotion, Skype for Pocket PC devices has been a big hit -- adding up to nearly 7 million downloads. This response is why Skype is looking at all devices such as BlackBerry and iPhone, but not sharing many details."

Silverman: "People don't want just voice, they are looking for presence and chatting."

In a video interview, Silverman and Malik discuss "the beta of Skype 4.0, the eBay relationship and the Skype-killer client being plotted by telecom operators amongst various things."

Over at BusinessWeek.com, Silverman told columnist Catherine Holahan about 30% of Skype's members use videoconferencing. Presence and chat are also hot.

Silverman told her: "Communication is being transformed without people realizing it."

He maintains: "The telephone companies are not going to invent the communications of the future."

Holahan responds: "Perhaps not. But in the U.S., it's the cable and telephone companies--not the new Web players such as Skype, Google Talk, and Jahjah--that have taken the lead in providing Voice over Internet Protocol (VoIP) services. These include Comcast (CMCSA), Time Warner, Vonage (VG), and Cablevision (CVC), according to research firm Telegeography."

She noted that Skype is helped in the mobile arena by recent moves by Google and Apple to open up handsets to third-party software. She said Skype has an application for the iPhone.

She added: "Already, Skype has seen some traction on the mobile phone. More than 7 million people downloaded the new version of Skype for Microsoft's (MSFT) Windows Mobile operating system since its launch last spring."
