Here is an even easier method to disable Apple's kill-switch mechanism.
Steve Jobs had clarified that Apple would use the kill-switch mechanism only to remove a malicious program
-- as an example a program that stole user's personal data just as we
had thought. He had mentioned:
"Hopefully we never have
to pull that lever, but we would be irresponsible not to have a lever
like that to pull."
So I would not recommend iPhone users to disable this mechanism, but if
you are paranoid about Apple having control over apps running on your
iPhone then you can read on for more details.
An even easier method is to download the latest BossPrefs app using Cydia Installer on your jailbroken iPhone. After its installed, launch it from your iPhone's home screen and choose the "Disable Apple App Killswitch". You can always revert back and allow Apple's kill-switch mechanism in case you change your mind.
does the firmware 2.0.1 for iPod touch have a killswitch?
