Realmware's Battlefield 3 Settings Editor!
This application was first released on the 6th of November, 2011, just after the release of Battlefield 3. It allows you to easily customise and tweak all of your Battlefield 3 settings, including the ones that aren't displayed on the in-game menu.
You can get started by checking out the features and screenshots, or just go ahead and download it now! You will need to make sure that you have the .NET Framework 4.0 installed.
BF3 Settings Editor 2.3 released!
We have now released version 2.3 of our BF3 Settings Editor! This release contains many new features, as well as some important bug fixes. We now have a fix for the jet brake, as well as support for themes and translations!

I don't know how well this would work with Aldo (rehab's) Battlefield 3 profile
