I have noticed that with my Otterbox Commuter, it is a little awkward to push the hard keys on the bottom of the phone. What I was wondering...is there any program or mod to add "permanent" virtual keys to the bottom of the screen? The acer and axis tabs have home, search, back, and menu keys on the screen at all times regardless of program. Any way to accomplished this on the Droid X so if you want to go back you push a button on the screen instead of the key on the bottom of the phone. Any ideas?
