You are right, PocketEarth did loose support for upside-down orientation recently due to Apple changing the way this works with iOS 6. Currently we still support iOS 4.3, and fixing it is a bit of work. Our next release, PocketEarth v1.5, will be our last update that supports iOS 4.3. After this, we will support only iOS 5.0 and later, and will be able to fix this issue with upside-down orientation more easily. So in short, yes we plan to re-add support for this, but it is two updates away, which means its likely a few months out. Sorry for the inconvenience, I will discuss it further with my team and see if there is anything we can do sooner!
