CampusM has now been released at Plymouth University. It's a mobile application for both Android and iPhone. This was very much a collaborative development project with input from numerous staff across the University. Searching 'Plymouth Uni' within the Android Market is all that is needed! The application is ~1.7Mb installed, so not likely to cause too much of a dent in on board memory.
More details on this application can be found on the Technology Enhanced Learning blog post (by Dr Neil Witt).
