iDiscrete JB adds some functionality that could not exist in the official App Store release. In addition to the App "Crash" option found under Protection Settings, the last three options on the main Settings page are unique to iDiscrete JB.
"Hide App As..." allows you to hide iDiscrete as an Apple app you don't use (I mean, no one uses that Contacts app, right??) Instead of the "Loading" screen to input your Touch Sequence, you will instead see a screen shot from the Apple app you choose to hide as. An unauthorized user would simply think that the app had frozen, and after your Timeout expires it will "crash" back to the springboard. Alternatively, if you don't want to use the Touch Sequence Protection™ feature, keep "Enable Protection" turned off and iDiscrete will masquerade as an Apple app in icon and name only; launching the app will boot directly into the iDiscrete Home Screen. Screenshots used in "Hide App As..." are kept in: /Applications/iDiscrete.app if you wish to use your own (OpenSSH required to browse file system). Note: using "Hide App As..." does not replace the original Apple app icon on the springboard. It simply renames and assigns a new icon to iDiscrete. For example, if you have iDiscrete hidden as Stocks, your springboard will have two Stocks icons: one for the real app and one for iDiscrete. If you wish to hide the original, we suggest SBSettings (available for free in Cydia).
The last two options should be very self-explanatory. Icons are kept in: /Applications/iDiscrete.app if you wish to use your own (again, OpenSSH required to browse file system).
WARNING! In all three of the above settings there is no text editor interface, and thus no opportunity to input your Reset Code if you forget your Touch Sequence. Therefore, the ONLY option if you forget your Touch Sequence is to delete and then reinstall iDiscrete (you will not be charged twice). Use at your own risk!
