Hello! I own a google nexus one! I have already suffered the first break of the home button, hardware defect common practice of this phone! with the passage of time and with the passing of pressure from the home button is broken ! I wanted to know if there is an app that would allow me to manage the unlocking of the lock screen with the trackball or the volume keys! I already tried the following programs: no lock: great but has the drawback that it locks the screen and I start several phone calls and crap when I put it in your pocket ... awkward LockBot: I do not like and I found the work that is right for me flyscreen: requires registration and permits too much for my taste you know you recommend a app or a solution? Thanks!
