Ok, I have confirmed this to work, and works well with imnut's mod to remove the sim warning.

This enables the apn editor under settings.
Go to Settings, More Settings, Mobile Networks, Access Point Names, menu button.
This is a flashable mod!
Note to rom devs: Feel free to use this, but give credit where due. Trust me, I will know if you kang it
Thanks for your work. I flashed it in recovery. However, under Mobile Network when I hit menu, my only option is reset to default just like before. I'm on Beans V2 ROM. Any help will be appreciated.
