How Update does work for iPhone App?
<p>I would like to know how update work for Apple store.
Does Apple delete all old data related to the old version of the application and then they install to newer one?
When user update a new version of any application, does the older version was deleted from his iPhone with all data ( pictures, database, sound,etc) and replaced by the newer version or not?
I update my application since few days and I think that Apple does not replace the old database SQLITE by the newer one.</p>
