After beta testing several builds, the latest updated version of MobileOrg for iOS has finally been released: https://itunes.apple.com/us/app/mobileorg/id634225528?mt=8 

Functionality is essentially the same as the previous version, just refreshed the various SDKs and updated the Dropbox API due to Dropbox deprecating v1. 

Please report any bugs to Github: https://github.com/MobileOrg/mobileorg/issues 

Much thanks to Mario Martelli and Boris for their invaluable help getting this release ready.
