Adobe took a new strategy to put Flash animations on the iPhone, with the release later this year of Flash Pro CS5 Beta, Adobe will enable any Flash developer to create an iPhone application (.ipa file) and then the developer could send it to Apple for approval.
So it is definitely for Flash games on the iPhone, unfortunately, no Safari plugin to be able to see flash animations on web pages.
I’ve just discovered an interesting web page from Apple explaining how to develop a web applications that is compliant with Safari for the iPhone. I think it’s a good idea for all the web developers that want to suit their application for this new device.
