My brother's Incredible finally died so he bought a Thunderbolt off of eBay. Seller said the screen and home, search, back, menu buttons didn't work. He bought a new screen and replaced it. Now the screen works but the buttons still do not. I thought I read somewhere a month or two ago about an app that simulates the hardware buttons on screen. I just can't remember the name of the app. Can someone point me/us in the right direction? Thanks!
