MobiOne 1.0m2 is the 2nd release in a planned series of incremental product improvements as we march towards a 1.0 production release. The central function of MobiOne to date is iPhone and Pre mobile web emulation. Thus you can test your mobile web apps and sites that are optimized for these 2 devices with MobiOne. Additionally you can test HTML5 sites and applications.
To get started, launch MobiOne and enter a URL of a mobile web app that you have an interest. Alternatively load a predefined bookmark by selecting the home button and then the bookmarks button. I hope this helps you get started.
Regards,
Wayne
