Here is a cab for people that want Internal Storage renamed to Storage Card.
And here is a cab that will re-enable SDAutorun so you can run it after you have renamed Internal Storage to Storage Card. This way you won't have to mess with your SDConfig.txt.
1. Install
Internal Storage to Storage Card.cab
2. Install
sd autorun config.cab
3. Soft Reset
4. Open File Explorer and run \temp\SDAutoRun.lnk
SD Autorun will now start and process your config file.
I normally use the "sd autorun config.cab" on new flashes because I like to test out a rom without any of my customizations first. So I just rename my config file before I flash, then rename it back when I'm ready to customize.
