Keep in mind one real IMPORTANT issue ... there are only about 128 MB  
memory available in the iPhone for all the apps. If there is an app  
consuming to much memory, then iPhone OS is simply killing this app,  
because there must always enough room left for an incoming call or SMS.

So of course it will be possible to handle a 4GB db on the iPhone,  
caching and many other things must be re-thinks twice, its not only  
about to recompile the libs and go.

Furthermore while there is indeed Obj-C 2 on the iPhone, it's NOT the  
full "standard", so especially the garbage collection is not  
implemented. The developer must care about memory handling. It's not  
only the issue of optimizing Valentina for a 4GB db with so many  
memory available, the developer must really wrap his brain about  
wrapping the data into the objects for the app.
