The
user data in the documents directory is backed up and can easily be restored.
As for model changes, if they are simple changes to the model between versions,
you may be able to get away with lightweight migration. It is a simple option
to add when loading the persistent store.
I have a problem with the core data object graph not properly persisting:
Managed Object A (Car) has a one-way, one-to-many relationship to several
Managed Object B's. (Tires)
When I create the object graph, I use the standard generated relationship set
mutator methods to setup the relationship

There is no API for changing the UITabBar. Yet, you can subclass the
TabBar
Your first comment was correct; they are unordered. The fact that they may
come back in the same order is not guaranteed by the API. Therefore, if you
need ordering, add an attribute to the core data object to do so.

You will need to log in using your dev account. Best of luck with
your application. While the lack of background processing is
problematic for many applications, there is still a large variety of

Long time lurker, first time to post.
I have a iPhone 3.0 application that is using core data in an
NSOperation to perform some updates. It is using it's own
NSManagedObjectContext connected to a common (with the main thread)
persistent store coordinator. Everything works great until the
