The mobile apps don't actually install on the phone. they are all web-based (and can therefore be accessed from a PC, too!).
The browser on your phone might not be capable of rendering the web page correctly, the only way to know if to try it (or perhaps find someone else with the same model phone who already has the plugin, and ask them!).
If you've been trying, and the page won't load, try loading it up from a browser on a different PC (not the one running AHP and the plugin). Also, you must keep AHP open when using the mobile plugins.
If that works, then it is a limitation in your phone. If that doesn't work, then something isn't configured right, and you might still have a chance.
