I just bought an Optimus V (2.2.1) , but the sw version is vm670ZV4.. I got it because I wanted a companion to tether or hotspot my nexus 7... have been going in circles trying to get the hotpot to pass data (it connects).. I don't mind rooting a phone, if I need to. But I am a newbie at android. By the way, I am also having trouble mounting a flash drive, although I have done everything short of rooting the nexus, though I would, if necessary.
I may be the very person that they were attempting to thwart, as I am on the $30/plan with unlimited 3g data...
