For all those outside the US (like me), I grabbed a copy of the APK using http://apps.evozi.com/apk-downloader/?id=com.google.glass.companion so if you want it you can grab it directly from there or on the link below which is from my Google Drive account.

The functionality where photos taken #throughglass  are available in the MyGlass app immediately for you to view, edit, share etc is awesome and works beautifully!

Enjoy!
