Apple Updates More Apps With iPhone Duo Support

Apple today updated its TestFlight and GarageBand apps with support for the iPhone Duo‘s inner and outer displays.

Both apps have the vertical toolbar and will now display properly on the ‌iPhone Duo‌ in any orientation.

TestFlight functionality is largely the same with little benefit from the Duo display, but GarageBand gets a wide layout that takes full advantage of the inner screen. It offers up a bigger interface for music editing and using touch instruments like keyboards and guitars.

TestFlight and GarageBand are both free Apple apps.
