Hey Melege,
The iPhone does not support flash, but if you make a basic interactive PDF with hyperlinks (not videos or audio) you can install the GoodReader application to interact with the PDF
As for Android and Blackberry. Some Android and Blackberry models do support flash, so you could view your presentation. Although on such a small screen it may be hard to interact with.
Device central is a way to test your documents on a variety of phones without having to own all of them. For more info on Flash mobile, check out this blog.
