i currently have iOS 4.0, and i don't want to upgrade yet. i had to uninstall ibooks, and when going to app store, it wont let me install until i upgrade to 4.2. any way around this? how can i get the older version of ibooks?
Guessing here, but maybe, jailbreak and ask someone to send you an old IPSW file. More details needed from the forum but think I'm pointing at a potential pathway.
