Data encryption with Core Data in iOS

Question

I just need a confirmation on this.

Is it correct to say that, with the iPhone 3GS and above, any data written to the filesystem is encrypted using hardware encryption? By simply creating the XXX.sqlite file on the file system, the data stored in it is already encrypted.

Also for further security NSFileProtectionComplete is provided?

Thanks.
