If you’re tired of using the hardware keys on your HD2 to navigate on your device, there is now a great alternative. Thanks to XDA member jerryfan2000 and pbk for developing a Sidebar like UI that allows you to use the hardware keys without touching them. This app is only for Android on the HD2 and not for WM builds. The installation is pretty simple as shown in this excerpt from the OP:
(1) install the apk
(2) When you click any of the 4 buttons first time(except close), you need to grant Button Savior root access. It happens only to your first ever button click.
If you want to learn more about it and give it a try, please check out the discussion thread and leave feedback for the developer. Thanks to Tom for sending this in!_________
