Small iphone app

Hi I need a small iphone app built for my personal use that will cloak or bypass my iPhone user password. The app will need to do the following... Enable the phone to be accessed without having to key in the existing password, or bypass the password by hitting a iPhone function key on the side of the phone or, Example: Lets say my password is: “GduLR/-6649” (as you can imagine having to key this in every time is a pain in the ass and time consuming). The app would enable me to add a cloaked version of the password for example: “1234” and it will let me into the phone yet still use the original password in the back end. Install: I won't be adding this to the apple store, i will need it to be hosted on my server and be easily added to an iPhone by using a url on my personal website and clicking on an "Add App" button. User interface: Once the app is installed, the user will be taken to a set up admin page where they would key in their existing password and then add the password of their choice and the time they want the auto lock to be. The admin page will need to display 1: Set an additional password, (the cloaked password) keeping the iPhone original password setting 2: Have a display are that has both passwords on the same screen 3: Lengthen the auto lock function so that the time between needing to re key in the password can be set for what ever time I want. For example, i may wish to have it be 5 minutes, 60 minutes, 6 hours, Thanks and good luck
