FileMaker Go is currently only available for the following devices
iOS 4.0 : iPod Touch, iPhone 3G / 3GS, iPhone 4
iOS 3.2 : iPad
I would file a feature request here : http://www.filemaker.com/company/contact/feature_request.html
Thanks - shame! But at least I have a real reason to use a new apple iPhone - never saw its appeal b4.
For the Blackberry you might want to check out FM Touch who has a version in beta, not quite the same as Go but might work also.
