The Sprint On Demand and Sprint Music are installed after a Hardreset as cab files. They aren't ROM files. If you look in your PPC's windows folder you will see several cab files that are loaded during the Sprint Customizations right after a hard reset. The cab files have the uninstall flag turned off not allowing you to uninstall. I took the two cab files in question from my phone and turned the uninstall flag back on. This should allow you to reinstall the cab files and uninstall them again. I have not tested this but it should work for you. Here are the steps.
1. Download the GroveMobile_pulgIn ondemand_6900.zip file
2. Install the first cab file.
3. Open your Rome Programs application in settings and remove the application you just installed.
4. Install the second cab file
5. Open your Rome Programs application in settings and remove the application you just installed.
6. Let me know if this removed everything.
