The cab only installs the DLLs and makes no changes to the registry whatsoever. I also set it up so it can be uninstalled if it doesn't work. It won't brick your phone.

The DLLs in the cab are signed with developer certs, so you will need to use the "security off" cab to install the certs for the phone to recognize the DLLs as being valid signed files.

If you got the DLLs from a dump, they are not signed at all because they are normally Modules and not regular files. I don't know if turning off security will allow you to use unsigned DLLs, but you could have a security issue there and you wouldn't get a warning either.

On the Titan, all settings are left default and your program needs to be set to COM4. Google Maps doesn't need any settings changed, just select "Use GPS". I have also heard it may be necessary to turn on Location in the Phone options.
