StartPatch is a homebrew application that patches your 4.1&4.0 System Menu in a similar fashion as StarFall.
Brick Warning
In the unlikely case that you lose power during patching process, you will brick. This will only happen if you lose power while the patches are being applied, and as this is a quick process, there is small risk of bricking. However, if you do brick, no one is responsible. There is no warranty with this app. You should take a BootMii NAND dump and have BootMii installed as boot2 (if possible) as a precaution.
Non-Brick Related Note
I have only tested the 4.0.4 USA version and cannot say if others work.
People will be asking "Why do other regions get higher versions than USA?"
Because the 4.0.4 is the version that works. I have heard about 4.0.6 not copying saves correctly but 4.0.5 (and 4.0.4) do have the correct versions for removing copy protection flags.
