Ok so I bought a learn to speak russian app for the iphone and i bought some language packs for it that cost extra money because its content within apps you have to buy. if i had to restore my iphone for whatever reason, would it still have the extra content back on it since it has connected to itunes (and itunes hopefully has it saved)? if its not transferable or whatever to a restored iphone (since it was originally on there), would i be able to email the people who made the app and ask to reload it for free?
