There are also a variety of frameworks that allow you to compile them into native apps for multiple platforms. They typically wont nail every platform, but they will provide a way to make native apps for multiple platforms at once.

Examples are:
Titanium Appcelerator
Rhomobile
PhoneGap

You best bet would be to develop a web application that users could access through the browsers on their devices. You wouldn't have access to some - possibly a lot - of the features on each phone, but you would be able to provide a similar look and feel between each device.
