Many devices out there only have three buttons, menu, back and home. The Augen Gentouch doesn't have volume buttons, only these three buttons. The easy fix for the PDN is the volume key hack, followed by the framework hack to restore the Notification bar functionality, then you install Bar Control from the Android Market and add your default launcher to Bar Control. Now when you want home you pull down the Notification window and press your launcher to return home. Easy.
