http://askubuntu.com – I am an old man who is interested in seeing the Ubuntu OS used more widely. I read the instructions for flashing the OS onto a Samsung Galaxy Nexus cell phone. I ordered such a phone. When it came I started to follow the instructions on this page: https://wiki.ubuntu.com/Touch/Install?action=show&redirect=TouchInstallP... I watched a couple of YouTube videos to guide me through the process. One video featured a young man who looked like he knew what he was talking about. He said that the Samsung phone had to be a "GSM" something, which the Verizon 4G model is not. I have three questio (HowTos)
