The MoodleTouch app (http://moodletouch.com) submitted an update to the app software already to address a few reported bugs and compatibility issues.
mTouch 1.1 is coming soon: We have received lots of useful feedback within the first two days and already applied some bug fixes and improvements. mTouch is now more stable.
We will be submitting an update (mTouch 1.1) 4/16 to the AppStore and hope that update will be downloadable within couple of days. (link)
