Code Genocide

KillExchangeLocks is a simple free iPhone application that helps the fact that with the new 2.0 Exchange support you can get locked into having a passcode and auto-lock setting on your phone. Even manually changing the plist you will then be asked to set a passcode again at least once a day. Instead of updating your plist everyday, just simply click on KillExchangeLock and your plist will be set to not require a passcode and never auto-lock.
