I have visited "MobileOrg 0.9 released!" at https://groups.google.com/forum/#!topic/mobileorg-android/AkhrwBCiLPU.
And download http://matburt.net/files/MobileOrg-release.apk.
But when I install this apk, it is v0.8.5 with no Ubuntu one support.
@matburt can you create and upload apks in the future?
I'm not sure why this fell through the cracks, but I've uploaded the version that's soon to be on the market...
