The smartphone's operating systems can (and are) updated. They are not  
circuits. The FSFE even leads a campaign called Liberate Your Device.

That said, free software is good. Even if it runs on proprietary operating  
systems. For instance, Emacs runs on Windows too. As for developing, Stallman  
himself had to use UNIX to replace it. Just make sure that you application  
runs on a free operating system (or as free as possible: check out the  
previous link). Otherwise, your application would potentially hinder the  
users to switch to freedom.
