The phone I could see, assuming you actually use it, o/w if it was an old smart phone and you had wifi, I could also see it.
I read the BB Playbook is starting to sell out for $250 in a few places, but a 7" screen doesn't interest me any more. (I've moved up to the 10" HP Touchpad, due to get GB in a few weeks.)
BTW, "Root" refers to just adding admin privileges to a device. If you're installing CM7, on your Nook, that's not rooting, but installing a custom rom. Are you rooting (stock rom) or installing CM7 on your Nook?
