Before Verizon there where no U.S. carriers in the CAG.
While this does not mean that Verizon will create a Ubuntu Touch device, it does give us hope that there will be one here in the continental United States.
As I posted here, Ubuntu Touch now runs natively on Android devices. What this means is that most current Android based phones could be given a native Ubuntu Touch install, and then sold via Verizon.
As an Ubuntu fan boy, I would love to have a Ubuntu Touch phone, but the reason non Linux lovers would want this phone is the way Ubuntu is thinking. This operating system will be very similar to the desktop/laptop version.
Most of the enhancements and applications available pc side will transfer to the phone and vice versa.
July 16th Update: MTN has also joined the CAG this week. To better illustrate the members of CAG, here is a little image for you:
MTN is based out of south Africa.
