I download the screenshot to use on my Nexus One (N1) but it can not run and said it requires root access. What is it, how can I allow that and what risks/notes to take when letting them the "admin" access like that?
Please see my related questions/answers here and here.

In short:


Root gives you full administrator access to your phone to do things that it normally cannot do (take screenshots, [free] wifi tethering, overclocking, etc).
You will void your warranty (but you can typically unroot your phone to a previous state that makes this point moot).
