I have come across a few articles stating that one can use the Apple Iphone Configuration Utility to create a profile containing a webclip that you can use to launch a hosted FM database in FMGo. I have even seen it work. But I haven't found any good documentation on how to make it work. I'm using a URL in the webclip of something like FMP7Script://myhost.com/mydb.fm7 but when I install the profile to my iPad it just opens a blank page in safari and stops.
Have you tried using the link that is produced by FMP when you select File->email link ?
Here is a link to a thread that may partially answer your question. I have not gotten it to work completely but maybe if our two minds meet we can figure this out!
One thing I found when using an App called IconProject that was suggested to me is that it puts an Http:// before my link and then takes out a part so it will not launch.
Hope this helps!
