hi, i'd like to understand something about app like xcomic or similar that download comic from internet and you can read inside the app.
1) is asked to register...why? what is the purpose of that? even in ruzzle you create an account...for what reason? gamecenter is not enough?
2) whan you click on a free comic there is no need to put a password, the popup that is always popping out when you make a normal purchase is not popping, is because does not pass through inapp-purchase but download from external server?
