Attached is a generic presentation that can be used to talk about uMobile. The presentation is in OpenDocument format.
There is an embedded video in the middle of the presentation that goes through a quick demo. There are some (admittedly cryptic) notes in the presentation on how to talk through the video portion. The video file is also attached separately.
There are also a number of screenshot slides available after the Q&A slide that can be used if a discussion of various features becomes relevant.
