Rumor has it Cable TV MSO VoIP provider Singlepipe is in play. Reports are they have interest from at least one competitor, Momentum Telecom.
A second rumor has it that Skype and Verizon Wireless have gotten chummy of late, and an announcement at next week's Mobile World Congress is being planned. If you look at history, Skype and Verizon Wireless have history. Skype already ran on a Samsung Windows Mobile smartphone some years back that was sold by Verizon. I recall calling Alec Saunders from Munich on that and also on a Sprint supplied HTC Windows Mobile device from that ran Skype too. While some may expect to hear that Skype is saying, "AT&T get lost," I don't think so. My intel tells me that Skype is working hard on a 3G optimized iPhone app but the to be announced play with Verizon is a way to show how 3G voice can work right sooner. My sources also tell me the play with Verizon was one that couldn't pass up as well. Candidly I wouldn't be surprised if this app runs on a BlackBerry, Android or maybe even the INQ phone that has been shopped around to mobile operators in the USA the last few months.
Other rumors has one of the leading consumer desktop video companies launching a mobile video client and more...
Time will tell.
