    Hmmm…why would I install an OS upgrade where I KNOW the touchscreen isn’t supported on a touchscreen phone?

    looking forward to when this port is…well, useful.

      WSeems stupid to me also what good is a touch screen phone which has no touch screen, bit of a no brainer not to install it.
