Cell Phone / WiFi phone combination

TMobile just launched a cell phone that can also make "free" wifi phone calls from a home WiFi network or TMobile hotspots. The minutes for the wifi calls do not count against your cellular minutes. You can get more details at http://www.theonlyphoneyouneed.com/. Here is some news on pricing at a blog I follow.

I was sure that one of the "4 orifices" (labeled by Walt Mossberg at the CTO Roundtable conference): Cingular, Verizon, Sprint/Nextel and TMobile, will soon jump on delivering wifi / cellular combination for phone. TMobile has a significant number of Wifi hot spots and was the obvious pick. I will love to get your views on who will go next.

This is another nail in the coffin of the "land lines" and cordless phones!
