Also a note based on our first wave of feedback:
This is not only about "Uploading to Commons". It is also about publishing images from your mobile device to Wikipedia articles, directly - see e.g. http://www.mediawiki.org/wiki/File:Mobile_upload_testing_2.PNG
This is a detail that might make a difference to many Wikipedia editors.
We have left notes on the Commons and English Wikipedia Village Pumps - see http://www.mediawiki.org/wiki/Mobile_QA/Commons_uploads#Promotion
