how to disable auto update in itunes
i have a jailbroken iphone, everything i sync with itunes it asks if i want to update to the current version 2.2.1.
i want to disable this in case one day i accidentally press 'update' and get to a version that will lock my iphone.
i have itunes 8 and i go to itunes->preferences->general-> then de-select 'check for new software updates automatically', but it still ask me when i re-lauch itunes.
am i missing something here? how do i disable this so i will not see that update window and update by accident?
