How to Disable the App Store Kill Switch Using Your Jailbroken iPhone

From Gizmodo -

The kill switch that lets Apple remotely remove applications on your iPhone can be disabled with the push of a button. All you need is a jailbroken unit and the updated BossPrefs app found on Cydia. Simply choose "Disable Apple App Killswitch" in BossPrefs. NOTE: if Apple wants to remove an app, they probably have a pretty good reason for doing so.
