interesting read on this
http://iphoneincubator.com/blog/data...orage-in-ios-5
from looking at this, apps should be able to store data in the documents folder of the app, I dont understand why apple say they dont want this as it would cause too much data to be backuped up to icloud/itunes.
I have apps that store data on icloud but give this as an option, so dont see apples problem
backing up to itunes has been the same since first ios device so dont see this as an issue
the tmp/cache directory that large amounts of data get stored in just seems wrong, imo this should be for things like internet cache
it really looks like a big disadvantage of ios 5 over previous versions
I have well over 10gig free on my device, if I want to fill this with kobo books it should be my decision, not apples
EDIT:reading a bit more on this and see the new options that tie in with number of books to store
if I tell the app to store all books (using the new dont backup/do not archive flag), do these books get stored in the documents folder or still in the tmp/cache area)
