I think this is appropriate to this thread: In case it hasn't been mentioned (I couldn't find the answer anywhere else), the reason the '4th' side of the cube (AKA iCube Side #2) doesn't show, is because of a registry miss-type. Both sides are pointing to the same application launcher.

HKEY_LOCAL_MACHINE\Software\HTC\Biotouch\Biotouch

App3 and App4 should NOT both point to CustAPLauncher.exe

Remove the 'Cust' from one or the other. Save and soft reset.
