This tweak does what the titles says – disables home button. IncarcerApp basically locks you in a particular app and disables the home button so that you do not return to the homescreen after pressing the home button. This is great for the little kids who often have a habit of clicking that little round home button which later annoys them because they cannot find their favorite clip that they were watching earlier.
You can lock them in the app by hitting the Volume up and then disable the lock by pressing the Volume down button. Oh, and the app is free too, but it does requires you to jailbreak your iPad.
After that, just search for “incarcer” in Cydia and click on install to download the app to your iPad.
