I'm working in an unofficial clone of the Moodle Mobile app for iPhone that works on Android and Blackberry devices (WebWorks, OS 6.0 and higher). It should work also on iPhone and iPad.
Phonegap enables you to build your app once with web-standards and deploy to multiple platforms.
Please note that this app is not a replacement or improvement of the official app for iPhone (and Android when available). It has beend designed to be a good starting point for creating your own custom app because is easily customizable and extendable using web technologies by anyone.
The app is currently an alpha relase with some bugs to fix and some functionallities not working fine
This post is a call for help for alpha/beta testers in Android and also BlackBerry
